You may not get everything you dream about, but you will never get anything you don't dream about.

To improve the golden moment of opportunity, and catch the good that is within our reach, is the great art of life.

Whilst part of what we perceive comes through our senses from the object before us, another part (and it may be the larger part) always comes out of our own mind.

Language is the most imperfect and expensive means yet discovered for communicating thought.

Truths emerge from facts, but they dip forward into facts again and add to them; which facts again create or reveal new truth (the word is indifferent) and so on indefinitely. The 'facts' themselves meanwhile are not true. They simply are. Truth is the function of the beliefs that start and terminate among them.

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