Okay you can't be too old. If you make really epic projects, then your friends won't care (or they might—IDK your friends but hopefully they wouldn't) if you say "I just picked this up to do this". Or, you don't tell them because you have plenty followers here (I notice your 40 subscribers).
That, or you can play servers meant for older people. Vindex Craft is a great city role-play server and I'm running my own bookstore now! It's all very mature, but not like bad or anything. My point is you can find a server of people your age who understand your problem and play the game with them! Hope this helped :D
