Honestly,
If this is your career path, That's what you want, I don't have an issue.
However, 3 Months of training won't do shit, I can tell you that now. If you "TRAINED" for 11 minutes, what do you think that did? All that's going to do is make you hot and sweaty and burn little calories that you already took in.
I think you need to rethink your decision when to play matches, for your own sake and dignity. "training" for 3 months won't do much. Take @ICEKILLER_99's advice and rethink your training plan, as well as @Collier's advice.
Do whatever and especially what you love (as long as it's not illegal LOL) but please take some advice in this thread. Over confidence can get the better of you and seeing how you're still young even this could fuck you up. 3 months is not a lot of experience in a sport like this.
You could also say fuck it, train till you're 16 and wreck shit that way if you're actually 14 according to Atomic.
