Nick Newell—winner of our Cage Potato bros’ Proving Ground competition—is an undefeated lightweight MMA fighter. He has speed, agility, strength and a healthy reserve of raw determination. What he doesn’t have is a left hand. You’d think that would be a disadvantage, but Newell doesn’t. He hasn’t stopped going since he first started wrestling as a kid. Watch this interview—complete with awesome fighting clips—and be inspired. We can all learn something from this guy. Namely, quit whining and kick ass.
