God damn f*&@#ing fat fingers!

I'm 45 and I made the 'brilliant' decision to learn the guitar now.

I figured that after listening to metal for over 30 years and the fact that I've hit a wall at work, I thought why not use what's left of my life and learn an instrument.

I've got a great instructor - college mate, a good friend and is a full time musician.

What can go wrong?

Well, the exercises he taught me (spider, crabwalk) - all were going well.

Then yesterday he taught me G chord, C chord - and I fucked up big time.

Besides the strange finger placement (to me, at least), i keep muting some strings. The chords sound so dull and lifeless.

Fucking fat fingers, man.

Please tell me there's hope and I can repurpose these sausages and play chords decently.

Any tips. (amputation is not a tip!)
