I started playing about a year ago and you may find it easier to work with an instructor to speed things up. You might be someone that is dedicated/disclipined enough to work on your weaker items and resolve the issue? Most of us enjoy practicing things we know, rather than things we don't.

My guitar teacher is very good at helping with the little nuances but as he always says, "I can show you the right buttons to press, but you still have to play it." Because you are just getting started, everything you learn at this point is probably new so the fun factor hasn't worn off. When frustration sets in and you don't have the personal interaction to help you through it, then you might be less likely to practice. Keep at it and remember to always have fun with it.
