Should i do mma, i don't want to become a quitter.?

Im 17 now, i did boxing for about six months, i know i was getting good, i could punch extremely hard, i even broke a heavyweigt fighters nose sparring, but eventually i just got bored with the whole thing, the repition and all, i even dreaded using my free time on it. Now i'm having feelings of wanting to return to fighting but mma instead, which i do like more than boxing. I just want it to be another phase like last time. Should I go for it?
