I don't know if you have ADHD, but I do. (Maybe you have it and it's undiagnosed.) I've found that rather than worrying about my own motivation or lack thereof, it's better to focus on sleep, exercise and diet. Get those things and "motivation" will come. If I'm not motivated, I try to improve those factors. I guess I'm saying that because it sounds like exercise is important to you as well.
