Show me a thoroughly satisfied man - and I will show you a failure.

Ideas without execution are hallucinations.

I am so deaf I am debarred from hearing all the time articulation and have to depend on the judgment of others.

The value of an idea lies in the using of it.

I have always consistently opposed high-tension and alternating systems of electric lighting...not only on account of danger, but because of their general unreliability and unsuitability for any general system of distribution.

There is a better way to do it - Find it!

Vision without execution is delusion.
