Re: I'm 0-7 should i quit?
I think the only one that can answer this question is you.
Does an impressive record matter? Or do you compete for the love of competing?
Did you lose 7 fights because you fought badly against weak novice opponents - or did you have wars with top opponents and just didn't get lucky?
In any case, I understand it can be humbling. But 21 is still young. You have plenty of time to turn it around if you want to.
