A little.
Been playing since I was 16, when I bought a slightly 'challenging' Eko acoustic guitar, the sheet music to the Stones Miss You and a chord book. "right, C, that finger goes there, that one there and those two there, strum, strum, strum, strum. OK, now Dm, that finger there, that one there and that one in between just there, strum, strum, strum, strum."
Presently play acoustic slide with Gospel Bell, rehearsing with a couple of friends with a view to a rock and blues band, and I've been playing in church for about 40 years. Currently have a few guitars and basses, bunch of amps (some I designed and built myself) a couple of pedal boards and a Roland guitar synth unit.
The thing about someone entering the room - that's also me. I can play on stage fine, with the largest audience around 1000 people, when It's just me in a room I can be very self conscious.
