Expect problems and eat them for breakfast.
Never complain and never explain.
Who seeks shall find.
If you think you can do it, you can.
Be thine own palace, or the world's thy jail.
Leap, and the net will appear.
The dog that trots about finds a bone.
After a storm comes a calm.
Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
All the mathematical sciences are founded on relations between physical laws and laws of numbers, so that the aim of exact science is to reduce the problems of nature to the determination of quantities by operations with numbers.
