If you're getting bored with it, as leonissenbaum said, try stepping away from it for a little while. Or you can explore other game modes you may not have bothered with before. Just look into different servers, mods, plugins, etc. Owning a server is super fun! Of course it's work (unless you prefer a very small server for a few close friends), and I suppose it isn't for everyone. You might also have more fun playing with friends (if not friends you know irl then MC friends). Oh, and you can even work on your own original creations. You should get into programming if you haven't already. Who knows, it could turn into one of your favorite passions! If that interests you let me know, I can point you toward some great resources.
Sure! To be honest, I'm really only ready to teach Java. I'm learning a few others atm but I'm not sure how much help I can be for those aside from listing recommended resources. So let me know what language I'd also be happy to help if you're having any trouble with your server. And just to be clear: No, I am not a power hungry tween looking for a staff position (I actually own a server as well ^^) . I just want to help because I like helping, and honestly, helping you would help me as well because teaching something is one of the best ways to really learn/master it.
Anyway, if you do decide you want to learn Java, I'll PM you some stuff. Sorry I can't be much help elsewhere.
