Success is the result of hard work.

Time is really the only capital that any human being has, and the only thing he can't afford to lose.

I've never made a mistake. I've only learned from experience.

When there's no experimenting there's no progress. Stop experimenting and you go backward. If anything goes wrong, experiment until you get to the very bottom of the trouble.

Success depends on how many experiments you can fit into 24 hours

One might think that the money value of an invention constitutes its reward to the man who loves his work. But... I continue to find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.

Let the public throw bouquets to the inventors and in time we will all be happy.
