My hunch is that you'll enjoy the studying and be very good at it. Much of it is down to motivation which I suspect you didn't have in 1980* but will do now if there's a clear end in sight.
Whichever route you take, good luck.

Four. It was going so well until you mentioned your favourite drummer. I'll give you two references:
1, American Psycho -- still can't work out whether BEE is being serious
2, "I'm talking Nonce Sense"
That's another thing about WFH (and I'm another who is -- now -- lucky enough to have my own office): you can do what you want to in there. Certain colleagues (tend to do admin work) need a perfectly organised desk and surrounding area; I'm not remotely interested in that, piles of paper that...
I'm the same. No need to travel, getting tea etc takes far less time, no distractions. If you want to speak to someone, there's always Teams, Zoom, etc.
