The more accurately you can think about who you are, what you want to accomplish and how to accomplish it, the more successful you will be.

What you concentrate on largely determines the quality and quantity of the results that you get and the success that you enjoy.

The happiest people in the world are those who feel absolutely terrific about themselves, and this is the natural outgrowth of accepting total responsibility for every part of their life.

Focus very clearly on a few small things. The purpose of a business is to give someone something that they want. Have a product or service that's really excellent. [...] What can you offer that no one else can offer and will satisfy them at a higher level than what anyone else can?

Persistence is self-discipline in action.

Your most important tasks and priorities are those that can have the most serious consequences, positive or negative, on your life or work. Focus on these above all.

Whatever we expect with confidence becomes our own self-fulfilling prophecy.
