I've been building for some 50 years, my problem is I can never build a kit stock, so sometimes I get stuck on the mods. I got so sick of one plane ( GP Super Sportster), that I just put it up for almost 2 years. Then one day I grabbed a saw and chopped off the front end and started over. It turned out great. Sometimes you have to get drastic, short of stomping on it. Building is 10% skill and 90% patience. Take a break, and come back to it later. Then finish it up the best you can and go fly it.
