I have not failed. I have successfully discovered 1200 ideas that don't work.

Ideas without execution are hallucinations.

The First 40 hours of work per week are for survival. Everything after that is for success.

To those searching for truth -- not the truth of dogma and darkness but the truth brought by reason, search, examination, and inquiry, discipline is required. For faith, as well intentioned as it may be, must be built on facts, not fiction -- faith in fiction is a damnable false hope.

Success depends on how many experiments you can fit into 24 hours

The perils of overwork are slight compared with the dangers of inactivity.

I do not believe in the God of the theologians; but that there is a Supreme Intelligence I do not doubt.
