If you think you can do it, you can.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
It's always too early to quit.
If you're going through hell, keep going.
Never complain and never explain.
Begin to be now what you will be hereafter.
You never know what motivates you.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
Frankly, the reason I joined MENSA is because I was dating a guy at the time who spoke five languages and could solve a Rubik's Cube literally with his eyes closed because it's just an algorithm.
