Nicely written Todd. This happens to me too especially when I am composing music. It sound like a hit in my head. Then I arrange it out on my computer and it sounds like the best think mankind ever heard. Then after listening and tweaking for a while, it sounds like complete rubbish and I am thinking I can’t bear listening to it again. Then I put it away promising myself I will come back to it. So I end up with hundreds of unfinished pieces on my drive.
Maybe i’ll read your article just before the next piece I do just to give me that crucial push to complete :) Thanks for the motivation boost!
