True genius resides in the capacity for evaluation of uncertain, hazardous, and conflicting information.

Work mixed with management becomes not only easier but more profitable. The time is past when anyone can boast about 'hard work' without having a corresponding result to show for it.

I don't believe in leaving things to luck. I believe in hard work and preparation.

Genius is not inspired. Inspiration is perspiration.

Sticking to it is the genius.

It takes a lot of hard work to make something simple.
