I make music, and a lot of it, but..

I make a lot of music, but most of it get's scrapped because I have all these things that go through my head, and they're basically all insecurities. Before I finish out that render on reaper, I just leave it hanging, as a project file never to be explored again. Barely do I ever post what I have to distrokid like I used to. I'm not sure if it's the judgment i'll get from the result of that music, or just simply that i'm holding myself to an impossible standard. I've been playing guitar for 11 years, piano for 13, and been producing for about 6 years. I know that i'm at least good enough to write good music, but i can't be the only one who scraps hours of work in a blink of an eye. Anyone else have this problem, if you have but gotten over it, what did you do to overcome it??
