From someone whose ambitions peaked around 1982, I will offer my two cents, if I may.
What I've found is that big lists are counterproductive for me. It looks so huge, so daunting...how will I ever do all that? Easier to do none. What works better is to write down one thing you want to accomplish the next day. Crossing it off is just as satisfying as crossing off a big list. Think of your list as a 'to be continued' thing. If you get more done...great, write those down and cross those off as 'accidental accomplishments' but only write down one thing for the next day.
Also, do not overestimate the size of your sock (that really wasn't intended to be double-entendrish like it sounds.) You might need a couple socks. And a sock might get lost in the dryer so it's always good to have spare socks. Less-stuffed socks are easier for transport too.
I've just always derailed myself when I look at the big picture of 'where I should be' and something I learned in the bin was to take smaller bites.
Really, I know you can do all of the things you want to accomplish. And you're going to feel really great accomplishing those things, if you don't put too much pressure on yourself.
You have a lot on your plate. I think your new start will give you energy and purpose unprecedented. Just don't derail yourself getting to the new start.
p.s. I have a smartphone, but for lists I use the old fashioned route: a small pad of paper. They're totally portable, too...I can't believe how small they're making pads of paper these days.
