Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

What you do today can improve all your tomorrows.

If you're going through hell, keep going.

I can, therefore I am.

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

Do not weep do not wax indignant. Understand.

Begin to be now what you will be hereafter.

Know or listen to those who know.
