I have been playing guitar for about 8 months now. I would say I'm progressing decently well, but my guitar teacher has one complaint against me: I don't use all my fingers of my fretting hand.
The fact is that I have REALLY long fingers. So for maneuvers a normal fingered person would have to use all fingers, I can manage equally well with just my index and middle finger. Only sometimes do I have to use my ring finger, and almost never my pinky.
My guitar teacher says that thought it's ok that i can play well with mainly two fingers, but not learning how to use all fingers will negatively affect me in the long run.
My question is: is my habit acceptable? Or will it really pull me back in the long run? Because I have to force myself to use my other two fingers which means playing becomes REALLY uncomfortable, though some other websites and sources say that "play how you feel comfortable".
All recommendations will be appreciated by me.
EDIT:Sorry, my internet connection was down so I couldn't view or reply any answers and comments. I think I need to get a little more specific. In chords SURELY I can't play with just two fingers, but say, while playing solos. I'm not too good in soloing, but am practicing to solo. In such cases I find it more comfortable to use two fingers rather than all 4.
In response to Graham, one of the answerers, I might have only 8 months experience, but I'm a faster than average learner, so I feel OK in trying to do basic solos.
Thanks to all those who have answered and helped.
