Be gentle to all and stern with yourself.
Never complain and never explain.
Always desire to learn something useful.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
Problems are not stop signs, they are guidelines.
If you think you can do it, you can.
To be a good loser is to learn how to win.
After a storm comes a calm.
Know or listen to those who know.
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.
