Know or listen to those who know.

You never know what motivates you.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

Begin to be now what you will be hereafter.

I can, therefore I am.

Do not weep do not wax indignant. Understand.

Quality is not an act, it is a habit.

Never complain and never explain.
