If you've got a talent, protect it.
You never know what motivates you.
Be gentle to all and stern with yourself.

Know or listen to those who know.
Without hard work, nothing grows but weeds.
The wise does at once what the fool does at last.
If you think you can do it, you can.
As a rule, software systems do not work well until they have been used, and have failed repeatedly, in real applications.
Whenever anyone says, 'theoretically,' they really mean, 'not really.'
