Problems are not stop signs, they are guidelines.
Go for it now. The future is promised to no one.
After a storm comes a calm.
Be thine own palace, or the world's thy jail.
Only the educated are free.
Never complain and never explain.
Always desire to learn something useful.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
If you've got a talent, protect it.
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.'
