Successful people are not people without problems. They are people who have learned to solve their problems.

The big thing is that you know what you want.

Ideas are elusive, slippery things. Best to keep a pad of paper and a pencil at your bedside, so you can stab them during the night before they get away.

Real evils can be either cured or endured; it is only imaginary evils that make people anxiety-ridden for a lifetime.

For a person to build a rich and rewarding life for himself, there are certain qualities and bits of knowledge that he needs to acquire. But there are also things — harmful attitudes, superstitions, emotions — that he needs to chip away. A person needs to chip away everything that doesn't look like the person he or she most wants to become.

People with goals succeed because they know where they're going.

You are responsible for how your life turns out, and your attitude shapes that life for better or worse.
