Gitarrist myself. It took me 4 years to show anyone my musical skills but taking the first step made me really proud and people seemed to like it same with youtube so far.I haven't told anyone yet! I guess I am jus nervous about what they would think. That and it is hard for me to share my music so youtube right now is a safe place I can do that. Maybe one day though!
I'm sure you'll get confident any time soon
