Things do not happen. Things are made to happen.
It's always too early to quit.
Never complain and never explain.
Be kind whenever possible. It is always possible.
Who seeks shall find.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
If you're going through hell, keep going.
Only the educated are free.
Without hard work, nothing grows but weeds.
That is a secondary teacher conception - the writer as an observer.
