Sounds like you possibly just have too much on your plate and you just can't focus. So much to do so you just can't get motivated for any of it. Maybe you just need a break from it all for awhile. Sometimes our hobbies can become too much like work, it has happened to me. Maybe a simple build or building something other than what you normally build will help. Maybe not. That's what works for me. Lately I built an airplane, a custom rod, a classic car. And now a race car followed by a vintage motorcycle.
