Do 100 pushups or situps in a row. Can't? Then do as many as you can and go for 10 more tomorrow. Go until you can do 100. Same with running and I hate cardio..go for a walk/run..then go further..then further.. Start a new hobie that you enjoy. Start a charity. Start a side business for extra money(this can be like I do and invest in my close/trusted friends dreams, be it by money or time/skills). I can keep going.
