Quality is not an act, it is a habit.
After a storm comes a calm.
The most effective way to do it, is to do it.
Always desire to learn something useful.
Never complain and never explain.

Be thine own palace, or the world's thy jail.
To be a good loser is to learn how to win.
You never know what motivates you.
If you re-read your work, you can find on re-reading a great deal of repetition can be avoided by re-reading and editing.
