You never know what motivates you.
By failing to prepare, you are preparing to fail.
Never complain and never explain.
Only the educated are free.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Who seeks shall find.
The dog that trots about finds a bone.
Problems are not stop signs, they are guidelines.
The most effective way to do it, is to do it.
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.
