No one should voluntarily remain in an environment which prevents his development.

The size of your accomplishments, the quality of your achievement, will depend very largely on how big a man you see in yourself, what sort of image you get of your possible self, yourself at your best.

The successful men of today are men of one overmastering idea, one unwavering aim, men of single and intense purpose.

This is the test of your manhood: How much is there left in you after you have lost everything outside of yourself?

Power gravitates to the man who knows how.

Nothing else so destroys the power to stand alone as the habit of leaning upon others. If you lean, you will never be strong or original. Stand alone or bury your ambition to be somebody in the world.

Money, influence, and position are nothing compared with brains, principles, energy and perseverances.
