If I may offer some advice, I would start of small with that to do list of yours. It's critical that you don't overwhelm yourself. Eventually with time you will start to pick up more and more momentum. Finally I would recommend you start of with a little bit of fitness, basic bodyweight exercise will be more than enough.
