Never complain and never explain.
Things do not happen. Things are made to happen.
Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
Only the educated are free.
If you think you can do it, you can.
Expect problems and eat them for breakfast.
The most effective way to do it, is to do it.
Quality is not an act, it is a habit.
I can, therefore I am.
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.
