One quick suggestion when it comes to footwear:

I have very big feet, and it's hard to find shoes that fit. Since I've only got one working hand, tying shoelaces is impossible.

Solution: Elastic shoelaces, which make my shoes fit snugly, but also make it possible to get them on and off easily.

(A long shoehorn helps, too.)

Once I was able to get my shoes on without help, I was able to move around a lot better and get out of the house much more frequently (including getting to the car to go for a drive).

The first day I figured this out, I went to a drive-thru while my wife was at work. I sent her a picture of my meal at home, and she was astonished that I'd made it out on my own. So was I, to be honest!
