Problems are not stop signs, they are guidelines.
After a storm comes a calm.
Be thine own palace, or the world's thy jail.
Never complain and never explain.
Do not weep do not wax indignant. Understand.
I can, therefore I am.
You never know what motivates you.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
Always desire to learn something useful.
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.
