Know or listen to those who know.

I can, therefore I am.

You never know what motivates you.

The wise does at once what the fool does at last.

The secret of getting ahead is getting started.

Go for it now. The future is promised to no one.

Do not weep do not wax indignant. Understand.

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.
