It sounds as if you need a reason to get back into things Wingman, join the transformation challenge, start a training journal (if you don't already have one), you need to let others hold you accountable mate. I and others will motivate your ass if you have a journal. Don't settle for mediocrity bud, get your shit together and take back control of yourself. Stop talking and start doing shit, like what Nike says....JUST DO IT!
Don't be a quitter mate, you owe yourself that much.
