If You’re Not Losing, You’re Not Learning

If you encounter someone who claims to have a perfect record, and says he has never lost in some field of endeavor, take the claim with a grain of salt. Statements like this often do not tell the whole story. If you want to learn and grow, you need to know that you're going to lose. And you will probably lose a lot! Someone with a perfect record may not have taken sufficient risks. If you cherry-pick all your battles, and never challenge yourself, you're not going to learn and grow.
