Just to be fair, he shouldn't be blamed for mistakes just because he works faster than everybody else. He already stated that he spends a lot of time planning, so these aren't just random unnecessary mistakes. Killemall, you do have skills, don't be so discouraged. Everyone makes mistakes....I'm not halfway done with my guitar yet, and I've already made plenty of mistakes. Just cheer up and have fun like everyone else says.
Just an idea.....perhaps you could take a short break from guitars and work on other projects (I dunno, furniture or something for example). You could do less critical projects that would still build your woodworking skills, that way when you build your next guitar, you will feel more confident. I don't know if that helps any....just trying to help. Believe it or not, you have been a help to people on this forum. Have a nice day!
