Know or listen to those who know.
Never complain and never explain.
Problems are not stop signs, they are guidelines.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
After a storm comes a calm.
Be gentle to all and stern with yourself.
Crabbed and obscure definitions are of no use beyond a narrow circle of students, of whom probably every one has a pet one of his own.
