Back in my youth I'd work all day at my real job then come home and work in my shop from 5pm to 10pm M-F and work about 10 hrs on Saturday. On Sunday I would go to shoots all day. Had to support a disabled wife and her 3 kids. I built a ton of guns back in the late 80's and early 90's, 10-16 a year. Now IF I get 3-4 hrs most days I'm lucky. Back is shot, neck is shot and so are my hands. I have tons of house and grounds maintenance to do. Discovering I'm mortal a couple years ago doesn't help stack up the shop hours either , I have a whole lot of fishing to do in the next twenty years before the grim reaper comes to take me, and that makes my attention span pretty short in the shop. I have Lindy rigs to tie, jig heads to cast, a boat to maintain.... Then I can be easily distracted by my reloading bench....the list goes on for ever.
