Never complain and never explain.
By failing to prepare, you are preparing to fail.
Quality is not an act, it is a habit.
Problems are not stop signs, they are guidelines.
You never know what motivates you.
The wise does at once what the fool does at last.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
Leap, and the net will appear.
Without hard work, nothing grows but weeds.
Attempt something so impossible that unless God is in it, it's doomed to failure.
