Learn to enjoy every minute of your life. Be happy now. Don't wait for something outside of yourself to make you happy in the future. Think how really precious is the time you have to spend, whether it's at work or with your family. Every minute should be enjoyed and savored.

Don't wait for change. You change.

Get into a line that you will find to be a deep personal interest, something you really enjoy spending twelve to fifteen hours a day working at, and the rest of the time thinking about.

Courage changes things for the better...[With courage you can] stay with something long enough to succeed at it, realizing that it usually takes two, three or four times as long to succeed as you thought or hoped.

Don't catch the bad and infectious attitudes of others.

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.

The big thing is that you know what you want.
