Be gentle to all and stern with yourself.
I can, therefore I am.
Leap, and the net will appear.
To know oneself, one should assert oneself.
It's always too early to quit.
Always desire to learn something useful.
If you've got a talent, protect it.
The dog that trots about finds a bone.
Never complain and never explain.
The wise does at once what the fool does at last.
That is a secondary teacher conception - the writer as an observer.
