You never know what motivates you.
Always desire to learn something useful.
Never complain and never explain.
Either you run the day or the day runs you.
Be kind whenever possible. It is always possible.
If you think you can do it, you can.
To be a good loser is to learn how to win.
Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.
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.
