While this may seem obvious, you can't go very far in go by yourself. If you don't have friends, teachers, competitors and other people you know who are interested in go, then you won't grow as fast as you could. This is one of the reasons I have so many friends on kgs. That, and having friends is fun and they are great people.
I suggest bringing your questions to sites like life in 19x19 their friendly forums have been a huge help to me.
