Never complain and never explain.
After a storm comes a calm.
If you've got a talent, protect it.
Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
Problems are not stop signs, they are guidelines.
If you think you can do it, you can.
That is a secondary teacher conception - the writer as an observer.
