If you've got a talent, protect it.
You never know what motivates you.
Do not weep do not wax indignant. Understand.
Never complain and never explain.
If you think you can do it, you can.
Well done is better than well said.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
The most effective way to do it, is to do it.
Quality is not an act, it is a habit.
But I don't think we'll go there until we go back to the moon and develop a technology base for living and working and transporting ourselves through space.
