Wherever you are - be all there.
Who seeks shall find.
Quality is not an act, it is a habit.
After a storm comes a calm.
Know or listen to those who know.
Never complain and never explain.
Be kind whenever possible. It is always possible.
Things do not happen. Things are made to happen.
What you do today can improve all your tomorrows.
The dog that trots about finds a bone.
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.
