Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
If you think you can do it, you can.
You never know what motivates you.
If you can dream it, you can do it.
Be thine own palace, or the world's thy jail.
Who seeks shall find.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
By failing to prepare, you are preparing to fail.
