The wise does at once what the fool does at last.
Only the educated are free.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Know or listen to those who know.
Problems are not stop signs, they are guidelines.
The dog that trots about finds a bone.
Never complain and never explain.
After a storm comes a calm.
To know oneself, one should assert oneself.
That is a secondary teacher conception - the writer as an observer.
