Go ahead, jump the gun
Having spent 30+ years composing, I used Garageband starting in 2004 to capture recordings of my compositions and kept squirreling them away online in stealth mode. March 2012 was the first time I felt I had a breakthrough when I completed Peisinoe, and I began to think seriously about officially posting my music including sheet music on eileensauer.com.
I would poke my head up periodically and think: I really should polish all of this up and throw it out there. In January 2014 when I realized I was still saying this, I threw in the towel and threw what I had over the fence. Otherwise, I knew in January 2015 I'd be saying: I really should polish all of this up and throw it out there...
That proverb "the perfect is the enemy of the good" is spot on.
So what's stopping you? Cut it out! Cough it up.
