If you've got a talent, protect it.
Well done is better than well said.
If you think you can do it, you can.
Know or listen to those who know.
The most effective way to do it, is to do it.
The dog that trots about finds a bone.
Always desire to learn something useful.
Either you run the day or the day runs you.
It's always too early to quit.
Quality is not an act, it is a habit.
So the thing I realized rather gradually - I must say starting about 20 years ago now that we know about computers and things - there's a possibility of a more general basis for rules to describe nature.
