There is time for everything.

I have not failed 10,000 times. I have succeeded in proving that those 10,000 ways will not work.

There is far more opportunity than there is ability.

Through all the years of experimenting and research, I never once made a discovery. I start where the last man left off... All my work was deductive, and the results I achieved were those of invention pure and simple.

The successful person makes a habit of doing what the failing person doesn't like to do.

I owe my success to the fact that I never had a clock in my workroom. Seventy-five of us worked twenty hours every day and slept only four hours - and thrived on it.

I never did anything worth doing by accident, nor did any of my inventions come indirectly through accident, except the phonograph. No, when I have, fully decided that a result is worth getting, I go about it, and make trial after trial, until it comes.
