Be gentle to all and stern with yourself.
If you think you can do it, you can.
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.
Never complain and never explain.
Only the educated are free.
If you've got a talent, protect it.
Begin to be now what you will be hereafter.
The most effective way to do it, is to do it.
The attempt to combine wisdom and power has only rarely been successful and then only for a short while.
