Howdy,
Congrats on finding the game and getting started!
I'm a little older than you (LOL... I'm 53) and started as an adult so I'm not going to be able to tell you a ton about starting as a young adult in house league.
What I can say is that playing hockey should be all about having fun learning about, getting better at, and playing the game, particularly in house league. If you're 14 and have just discovered hockey, one of the things you're going to run into is players that have been playing since they were 5 and are crazy good, etc. etc. Don't let it get you down when you can't do the stuff on the ice that those people can do. Just keep working at it, keep having fun, and before you know it you'll be pretty good too. π
Welcome! I'm jealous of you starting playing before your knees are worn out, while you're still flexible, etc. π Mark
