Hi there.
Just about your lesson thing and how your afraid it'll turn into work or something, that couldn't be further from the truth.
I haven't been playing as long as you, but I have taken lessons, and in my two years of playing I have taken a lead and rhythm guitar position in a band that was featured on the Juno awards. (Big Canadian music show) And my lessons have been great. I've picked up so much theory and technical knowlege that it makes learning songs a lot easyer.
So dont worry about lessons turning into work or not being fun or anything, they can really help you.
