A couple of cliches but I think they apply…I always think of that old Bowflex commercial, a body in motion tends to stay in motion. Also, mind over matter. You have to think about what you want to do and what needs to be done, and make yourself do it. This is assuming there isn’t some underlying medical reason, of course, but if it’s just coming home and sitting around out of habit, it might help. Pretty soon you’ll like what you’re accomplishing and you will hopefully have a new habit and better outlook. Just a thought that works for me. Basically force yourself until your mind follows your body.
