Learn to depend upon yourself by doing things in accordance with your own way of thinking.

A rumor is like a check--never endorse it till you're sure it's genuine.

The quality of your thoughts determines the quality of your personal character.

Be an earnest student of yourself. Study your leading desires and tendencies.

Good humor is a tonic for mind and body. It is the best antidote for anxiety and depression. It is a business asset. It attracts and keeps friends. It lightens human burdens. It is the direct route to serenity and contentment.

When you want a thing deeply, earnestly and intensely, this feeling of desire reinforces your will and arouses in you the determination to work for the desired object. When you have a distinct purpose in view, your work becomes of absorbing interest. You bend your best powers to it; you give it concentrated attention; you think of little else than the realization of this purpose; your will is stimulated into unusual activity, and as a consequence you do your work with an increasing sense of power.

To every problem there is already a solution, whether you know it or not. To every sum in there is already a correct answer, whether the mathematician has found it or not.
