Working at something you don't care about is the very best way to waste your life.

Everything you have in your life, you have attracted to yourself because of the way you think, because of the person that you are. You can change your life because you can change the way you think.

The better you get at your key skills, the more you accomplish in a shorter period of time.

To be successful, you need to really work hard. And every study in the last 50 years says that successful people say, "I am not smarter than anybody else. I just want to work harder and longer."

An undefined goal is unreachable.

Superior leaders are willing to admit a mistake and cut their losses. Be willing to admit that you've changed your mind. Don't persist when the original decision turns out to be a poor one.

The great secret to success is that there are no secrets of success. There are only timeless principles that have proven effective throughout the centuries.
