Never complain and never explain.
Quality is not an act, it is a habit.
Expect problems and eat them for breakfast.
Do not weep do not wax indignant. Understand.
If you've got a talent, protect it.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
I can, therefore I am.
The dog that trots about finds a bone.
If you can dream it, you can do it.
Diversity in the world is a basic characteristic of human society, and also the key condition for a lively and dynamic world as we see today.
