Always desire to learn something useful.
Quality is not an act, it is a habit.
After a storm comes a calm.
Expect problems and eat them for breakfast.
Things do not happen. Things are made to happen.
Never complain and never explain.
The secret of getting ahead is getting started.
To know oneself, one should assert oneself.
The dog that trots about finds a bone.
You never know what motivates you.
For the greater beauty of the instrument, the balls representing the planets are to be of considerable bigness but so contrived, that they may be taken off at pleasure, and others, much smaller, and fitter for some purposes, put in their places.
