William James

How to gain, how to keep, how to recover happiness is in fact for most men at all times the secret motive of all they do, and of all they are willing to endure.

The ideas gained by men before they are twenty-five are practically the only ideas they shall have in their lives.

Success or failure depends more upon attitude than upon capacity successful men act as though they have accomplished or are enjoying something. Soon it becomes a reality. Act, look, feel successful, conduct yourself accordingly, and you will be amazed at the positive results.
