William James

Act as if what you do makes a difference. It does.

The greatest discovery of my generation is that a human being can alter his life by altering his attitudes.

Believe that life is worth living and your belief will help create the fact.

The greatest weapon against stress is our ability to choose one thought over another.

Success or failure depends more upon attitude than upon capacity.

Nothing is so fatiguing as the eternal hanging on of an uncompleted task.
