Either you run the day or the day runs you.
Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
To know oneself, one should assert oneself.
The dog that trots about finds a bone.
Only the educated are free.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
If you're going through hell, keep going.
Always desire to learn something useful.
That is a secondary teacher conception - the writer as an observer.
