Never complain and never explain.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
I can, therefore I am.
Well done is better than well said.
If you've got a talent, protect it.
By failing to prepare, you are preparing to fail.
Quality is not an act, it is a habit.
Leap, and the net will appear.
If you think you can do it, you can.
When the traveler goes alone he gets acquainted with himself.
