Know or listen to those who know.
Only the educated are free.
Things do not happen. Things are made to happen.
I can, therefore I am.
Do not weep do not wax indignant. Understand.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
Quality is not an act, it is a habit.
Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
There were no PCs when I started programming on computers.
