Do what you can with what you've got wherever you are.
Look for a situation in which your work will give you as much happiness as your spare time.

Take time for all things: great haste makes great waste.
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.

If a man takes one day off, it takes him about three days to get the harness fitted again.
Never mistake motion for action.
Striving for excellence motivates you; striving for perfection is demoralizing.
