I am not discouraged, because every wrong attempt discarded is another step forward.

I failed my way to success.

No, I haven't failed thousands of times. On the contrary, I have successfully eliminated thousands of ideas that do not work!

I owe my success to the fact that I never had a clock in my workroom.

I have not failed. I've just found 10,000 ways that won't work.

Suspicion and jealousy never did help any man in any situation.
