Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
Always desire to learn something useful.
The wise does at once what the fool does at last.
To know oneself, one should assert oneself.
If you think you can do it, you can.
Who seeks shall find.
If you can dream it, you can do it.
Be thine own palace, or the world's thy jail.
If you've got a talent, protect it.
