If you think you can do it, you can.
Well done is better than well said.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
The secret of getting ahead is getting started.
Without hard work, nothing grows but weeds.
Leap, and the net will appear.
You never know what motivates you.
To be a good loser is to learn how to win.
Always desire to learn something useful.
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.
