Who seeks shall find.
If you're going through hell, keep going.
If you can dream it, you can do it.
If you've got a talent, protect it.
Be kind whenever possible. It is always possible.
Be thine own palace, or the world's thy jail.
Quality is not an act, it is a habit.
Begin to be now what you will be hereafter.
Well done is better than well said.
Always desire to learn something useful.
