To know oneself, one should assert oneself.

Know or listen to those who know.

Well done is better than well said.

Either you run the day or the day runs you.

If you think you can do it, you can.

Expect problems and eat them for breakfast.

Do not weep do not wax indignant. Understand.

Never complain and never explain.

The most effective way to do it, is to do it.
