start singing again

i love to sing but have terrible shyness/timidity about it. The worst part is that I am surrounded by opportunities to sing and I don’t take them. To wit: my husband is a recording engineer and we have a studio in our house! Which I never use!! We have many musician friends. There is an informal weekly jazz jam a few miles away where singers are welcome to join, but I clammed up when my husband brought me there. You get the idea.
I was a member of a jazz choir for a while, took some vocal lessons, but kind of let it all go. I’ve said for years that I want to perform but so far I’m not making it happen. I can karaoke like nobody’s business, but I want to feel comfortable enough to belt it out and ham it up WITHOUT having a drink in my hand.
So for the time being: what’s my goal? to pick a song I could sing at the jazz jam and practice it until I feel comfortable with my rendition. Then let go of the need to sing it “perfectly”. Remember that a gift (as in a talent) is so called because its meant to be GIVEN AWAY not hoarded and locked up secretly.
