Well done is better than well said.
Only the educated are free.
The wise does at once what the fool does at last.
Be thine own palace, or the world's thy jail.
The most effective way to do it, is to do it.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
It's always too early to quit.
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.'
