The man who has done his best has done everything. The man who has done less than his best has done nothing.

The inventor, the man with a unique, specialized talent, is the only real super-genius. But he is so rare that he needs no consideration.

The men who miss success have two general alibis: 'I'm not a genius' is one; and the other, 'There aren't the opportunities today there used to be'.

Don't be reluctant about putting on overalls!

Most talk about 'super-geniuses' is nonsense. I have found that when 'stars' drop out, successors are usually at hand to fill their places, and the successors are merely men who have learned by application and self-discipline to get full production from an average, normal brain.

Bare hands grip success better than kid gloves.

The real test of business greatness is in giving opportunity to others.
