The value of a good idea is in using it.

I believe in the existence of a Supreme Intelligence pervading the Universe.

Of the 200 light bulbs that didn't work, every failure told me something that I was able to incorporate into the next attempt.

Unfortunately, there seems to be far more opportunity out there than ability.... We should remember that good fortune often happens when opportunity meets with preparation.

Show me a completely contented person and I'll show you a failure.

I never once failed at making a light bulb. I just found out 99 ways not to make one.

People are not remembered by how few times they fail, but by how often they succeed. Every wrong step is another step forward
