It's always too early to quit.
After a storm comes a calm.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
The dog that trots about finds a bone.
You never know what motivates you.
Always desire to learn something useful.
Expect problems and eat them for breakfast.
If you can dream it, you can do it.
Who seeks shall find.
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.
