The most-quoted Thomas Edison line about trying again is short enough to fit on a sticky note: “I have not failed. I’ve just found 10,000 ways that won’t work.” Paired with “Our greatest weakness lies in giving up,” it is the pair most people mean when they search for quotes about Thomas Edison and trying again. One caution before you use either: several popular sayings carry Edison’s name loosely, so I’ve flagged the shaky attributions below.
“Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.”
— commonly attributed to Thomas Edison
Thomas Alva Edison (1847-1931) was an American inventor and businessman whose Menlo Park, New Jersey laboratory turned out hundreds of devices, including a durable incandescent light bulb, the phonograph, and motion picture equipment. He was also partially deaf, and most of his work was done by a large team of technicians rather than alone. That detail matters here, because the persistence in these quotes was real while the lone-genius story is mostly a myth.
What follows is a working collection: ten quotations about Thomas Edison and trying again, what each one actually argues, and a real situation where you could use it. Read the attribution notes before quoting any of them in print or on a card.

1. “Our greatest weakness lies in giving up.”
This line argues that the decision to stop is the failure, not the result that didn’t arrive. The second sentence in the longer version, “The most certain way to succeed is always to try just one more time,” is the part that does the practical work: it converts a vague pep talk into a specific, countable action.
Where it fits
A support engineer whose suggestion was shut down can send this in a follow-up email, with one line on what they would change in the next proposal. Wording matters there: pair it with the actual revision plan, or it reads as a nudge rather than a reply.
A caution on sourcing. The line circulates in motivational collections under Edison’s name without a specific date, letter, or recorded occasion. Treat it as widely attributed rather than documented.
2. “Genius is one percent inspiration and ninety-nine percent perspiration.”
This is the best-documented quotation in the collection. Edison wrote variations of it in his own laboratory notebooks in the 1890s and 1903, phrasing it around the idea that a small amount of inspiration does little without sustained labor.
The practical reading is about ratio, not romance. If a task is going badly, the question it answers is whether you have done enough unglamorous repetitions. Practice a passage twenty times, rewrite the same paragraph for a week, run the same test with one variable changed.
It is a poor fit for someone who has not started. Effort cannot substitute for choosing the right problem, and the line says nothing about strategy.
3. “Failure is the stepping-stone for success.”
The stepping-stone image says a failed attempt is a raised level you can stand on to see further. A failed business pitch is useful if it tells you which of the three concerns the room reacted to. A failed month of sales is useful if it isolates the one customer type you keep losing.
Try naming the change in one sentence before you repeat the attempt. A small bakery whose weekend market stall underperformed could test a single change, like pre-paid pickup boxes, rather than reopening the whole operation. If no honest sentence can be written, the honest conclusion may be that the idea needs replacing.
This wording is compiled and repeated across many Edison collections. The underlying idea is consistent with how he described his own work, though I would not present this exact sentence as a sourced quote.
4. “Success is the sum of small efforts repeated day in and day out.”
This one is about accumulation. Any habit you want to build already belongs to someone who did it badly for a while before it turned into a skill, so the useful move is to lower the size of the daily step until you can actually repeat it.
Try a version you would not put in a motivational poster. Twenty minutes of Spanish on weekdays. One page of writing on Sunday. Six sales calls before the first email goes out. If the smallest version feels embarrassingly small, that is usually the size that works.
A weekly review beats a daily one for most people. Which repetitions happened, and which got quietly dropped?
5. “The only way to do great work is to love what you do.”
Read carefully, this is a statement about endurance rather than a guarantee. Love of the work, in this reading, means the thing still interests you on the hard days. Where that interest has genuinely gone, the quote stops being advice and starts being a demand.
For a student choosing between two subjects, the question is which one you would still open on a wet Tuesday with no deadline. For an employee weighing a job change, it is whether the boredom is a phase of the work or a permanent feature of it.
Reflection prompt: list three things about the task you still find genuinely interesting. If the list is empty, that is useful information, and it points toward a change rather than more effort.
6. “There is no failure. Only feedback.”
This is a coaching formulation from the late twentieth century, not an Edison line, and it circulates with his name attached. Say it out loud and the flaw shows: failing a driving test is not simply feedback, and a business that runs out of money is not merely a data point.
It becomes accurate with a small amendment. Failure that produces a recorded lesson is feedback. Failure that repeats the same mistake unchanged is just a repeat.
Make the loop concrete: write down what happened, what you expected, what you will change, and when you will check. A team shipping a feature that converts badly can log the assumption, change one element, and re-measure. The discipline is the whole value, and it is what the quote gestures at.
7. “Opportunities don’t make themselves. You create them.”
This line reframes passivity as a choice. After a rejection, the difference between two candidates is often what each does in the following month, and the one who applies somewhere better usually did it deliberately rather than by waiting for an invitation.
Preparation is the mechanism. A portfolio piece finished after a project ended, a conversation with someone who works where you want to be, a rewrite of a portfolio piece you already had. None of these guarantees anything, and all of them are things you control on a Tuesday afternoon.
On the job market, this is the one I would use after a layoff. Set a small weekly number, like three conversations, and track it the way you would track sales calls.
8. “I have not failed. I’ve just found 10,000 ways that won’t work.”
This is the version of the line almost everyone means, and the exact wording has never been traced to a dated record. The story usually told goes like this: a young assistant at Menlo Park asked Edison when he would finally succeed at the light bulb, and Edison replied that he was getting closer with every attempt. The assistant, depending on who is telling it, had asked the question sarcastically or hopefully.
Edison did describe his testing method in terms of eliminating bad options, and reports of his experiments around the bulb run into the thousands of individual trials. What the number is not is a verified count. Treat 10,000 as rhetoric that communicates the scale of the search.
What the idea does well
An unsuccessful method that you understood is data. In research and engineering, the list of approaches already ruled out is the most valuable document you own, because nobody else has to pay for that work again. Keep the version number, the assumption, and the result for anything you try twice.
The weak point is honest and worth naming. Reframing helps when the method was wrong. It does not help when the goal was wrong, and the relentless version of the story can pressure people to keep pushing a project that should have ended. A founder who left a construction job for a failed venture used to say in forum discussions that they would not call it a failure unless they gave up trying again, which is a healthy definition, but it is also easy to apply too generously.
9. “The best way to predict the future is to invent it.”
The insight here is that most of what people call the future is a decision someone already made. That reframes a setback: if the conditions changed, the right response is to design the next version rather than to guess at it.
Consider a designer whose main client moved in-house. Predicting the future means guessing what the new department wants. Inventing it means building a small course, or a productized version of the process, so that the answer is partly yours.
Worth being skeptical of the line as a slogan. Inventing the future is slow, mostly unglamorous work, and the framing flatters founders more than employees. It is most useful when paired with a deadline.
10. “My best work is yet to come.”
A forward-looking line rather than a story about effort, and the most frequently repurposed of this set for a reason: it is short, and it can be said sincerely after a bad review or a bad year.
It works best with evidence attached. After a difficult performance review, it is weak on its own and useful when followed by the two things you will change, plus a date to revisit them. After a year of freelance work, it is stronger when you point at the specific client type that paid best and the one you want more of.
Be careful using it publicly. The gap between this line and a company announcing a layoff is a large one, and using it there tends to land badly. The forum conversations about it are split for that reason: some readers use it as a self-talk tool, others say relentless framing is not helpful when someone needs rest or a different direction.
Frequently Asked Questions
What is the most popular Thomas Edison quote about trying again?
It is the line usually rendered as “I have not failed. I’ve just found 10,000 ways that won’t work,” often paired with “Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.” Both circulate widely under Edison’s name, though the exact wording of neither has been traced to a dated record.
Are all motivational quotes attributed to Thomas Edison authentic?
No. The perspiration line appears in variants in his own laboratory notebooks, which makes it the best documented of the set. “There is no failure. Only feedback” is a later coaching formulation, and several others come from compiled collections with no clear original source. Check a notebook, letter, or speech before calling a line an exact quotation.
How can I use Thomas Edison quotes in a presentation?
Use one, briefly, next to a concrete fact of your own. A single line followed by what you changed after the setback works far better than a slide of quotations. Skip it if the room has just heard bad news, since motivational framing tends to read as tone-deaf there.
What did Thomas Edison mean by one percent inspiration and ninety-nine percent perspiration?
He meant that results come from sustained labor rather than from sudden insight, which is why the ratio is weighted so heavily toward work. In practice it points to repeated, unglamorous effort on a chosen problem, such as daily practice or repeated testing, and it says nothing about choosing the right goal.
Can I share Thomas Edison quotations on social media?
Yes, and quoting a short line with attribution is normal practice. If a line is contested, say so in a few words rather than presenting it as exact, which takes seconds and protects your credibility with readers who already know the history.
How do I explain a failure without sounding negative?
Describe what happened, what it ruled out, and what you will change next time. That order moves the conversation from the result to the method, and it is more useful to a listener than a summary of the outcome. Keep the failure to one sentence and spend the rest on the next step.
Conclusion
Quotations about Thomas Edison and trying again are most valuable when they change a decision. Each line here argues for something slightly different: keep going after a rejection, repeat the small efforts, record what an attempt ruled out, build the opening yourself, or accept that the goal was wrong.
Pick one, and use it where it fits rather than as decoration. The perspiration line suits a study plan. The 10,000 ways line suits research and experiments, and only if the method is what failed. The giving-up line suits the day after a rejection.
And keep the attribution straight when you share it. Saying “often attributed to Edison” costs you nothing and earns you more trust than a confident misquote. This collection was checked in 2026, and the sourcing notes above will tell you which lines hold up and which are worth enjoying as folklore.
