Manage by objectives. Tell people exactly what you want them to do and then get out of their way.

Happiness and high come to you when you choose to live your life consistent with your highest values and your deepest convictions.

You have to set big goals for yourself. And you have to put aside all the negativity in your life that tells you that if you came from a certain education or a certain family background that you can't achieve big goals. That's one of the things that America has.

Your persistence is your belief in yourself.

You can't help the poor by becoming one of them.

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

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?
