Quality is not an act, it is a habit.
Never complain and never explain.
If you've got a talent, protect it.
Be thine own palace, or the world's thy jail.
I can, therefore I am.
You never know what motivates you.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
After a storm comes a calm.
Well done is better than well said.
The best museums and museum exhibits about science or technology give you the feeling that, hey, this is interesting, but maybe I could do something here, too.
