To be a good loser is to learn how to win.
Who seeks shall find.
What you do today can improve all your tomorrows.
It's always too early to quit.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.
You never know what motivates you.
Begin to be now what you will be hereafter.
If you think you can do it, you can.
