I owe my success to the fact that I never had a clock in my workroom. Seventy-five of us worked twenty hours every day and slept only four hours - and thrived on it.

Do the thing and the power will come.

I have better use for my brain than to poison it with alcohol. To put alcohol in the human brain is like putting sand in the bearings of an engine.

I am quite correctly described as 'more of a sponge than an inventor....'

The doctor of the future will no longer treat the human frame with drugs, but rather will cure and prevent disease with nutrition.

It is astonishing what an effort it seems to be for many people to put their brains definitely and systematically to work.

The thing I lose patience with the most is the clock. Its hands move too fast
