Wherever you are - be all there.
Problems are not stop signs, they are guidelines.
Leap, and the net will appear.
It's always too early to quit.
Only the educated are free.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
Be kind whenever possible. It is always possible.
The dog that trots about finds a bone.
If you've got a talent, protect it.
That is a secondary teacher conception - the writer as an observer.
