Today the greatest single source of wealth is between your ears.

Whenever you complete a task of any size or importance, you feel a surge of energy, enthusiasm, and self-esteem. The more important the completed task, the happier, more confident, and more powerful you feel about yourself and your world.

The foundation of confidence in virtually every field is preparation.

Proper business planning demands that you focus on the self-interest of the customer at all times.

Do one small thing immediately - often this is all you need to do to get started.

The only real antidote to worry or problems is systematic, purposeful action in the direction of your goals.

When you work towards your goals, you become healthier and healthier, mentally. It is very hard to do with a negative attitude. You just need to become more and more positive. And then you start to succeed. And starting to succeed is like winning a race and having the audience cheer. That makes you feel happy and motivates you to work even harder and achieve even more.
