To know oneself, one should assert oneself.

Never complain and never explain.

What you do today can improve all your tomorrows.

Without hard work, nothing grows but weeds.

Expect problems and eat them for breakfast.

Do not weep do not wax indignant. Understand.

Well done is better than well said.

Know or listen to those who know.

By failing to prepare, you are preparing to fail.
