Obstacles are those frightful things you see when you take your eyes off your goal.

There are three things that grow more precious with age; old wood to burn, old books to read, and old friends to enjoy.

It has been my observation that most people get ahead during the time that others waste.

You can't build a reputation on what you are going to do.
