Keon is an idiot, and I know what it is to be far from your family for a long time without being able to call. Time is time, it passes
But when his little girl turns 16 and she wants to buy a sh*tload of stuff he can't afford because he's just a nobody trying to make it to the end of the month, he'll remember and think "man, I wish I gave it a shot"
quitting with this attitude is almost a 100% guarantee he'll never make a living out of it, let alone a comfortable life.
if he cared that much for his daughter, he'd have stayed because this is a life changing experience, if you can hold your own on TUF even if you don't win it, you still have a decent chance of making it into the octagon.
