Just take a break from it for a few days and then see how you feel. We all go through this from time to time and if you ever plan on doing scale then get use to not seeing the end in sight. Try and not think that way as that will cause you a lot of frustration. It took me 18 months off and on to finish up the Corsair that's on my web page as I would get tired of working on it. Lot of times I will have a second less work intensive plane going also and that helps cut the bored feelings. Take a break and spend some time in front of the stupid tube, works for me!!!!
