Good luck with your goals! If you keep working at it slowly, you will get there in time. Plus, remember not to judge it on the mirror, judge your success on how much better you feel, because that will probably come a lot before visible results. With the exercise, the easiest way I've found to stick with it it to find something that's enjoyable for you and keep it that way. If you hate running, don't run, swim or cycle - there's so much you can do. If you find yourself not liking it and finding sticking with the routine hard, switch to something else to find the fun factor again.
You can do it! Plus the forums here will be supporting you all the way.
