Serious development of the personality begins at the closet door.

Psychology saves us from mistakes. It makes us more clear as to what we are about. We gain confidence in respect to any method which we are using as soon as we believe that it has theory as well as practice at its back.

As there is no worse lie than a truth misunderstood by those who hear it, so reasonable arguments, challenges to magnanimity, and appeals to sympathy or justice, are folly when we are dealing with human crocodiles and boa-constrictors.

In business for yourself, not by yourself.

We are proud of a human nature that could be so passionately extreme, but we shrink from advising others to follow the example.

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.

The love of life, at any and every level of development, is the religious impulse.
