Being newly-retired, (as of three days ago), this forced seclusion is going to be interesting. Heck of a way to start out, though, I must say. I'm extremely happy we didn't have some super-vacation planned for the day after I stopped working. As it is, it's been like a looooong weekend.
I'm approaching it not so much as "isolating myself at home," as, "Ok, you wanted to retire - now, here it is. Deal with it."
My list of things I want to do is lengthy, and seems to be growing every day. Everything from gardening and landscaping chores, to painting the inside and outside of the house, remodeling three bathrooms, replacing carpet with hardwood on the second floor of our home, cleaning and decluttering everything from attic to basement (if we had a basement), learning how to properly groom my two dogs myself, spending quality time organizing my home computer network files and data storage, and any number of one-off, on-the-day things. Not all of it I'll do myself, but for the things that require outside workmen, coordination of the process is necessary. When all else is done, I have a few dozen books I want to read.
Bottom line, I do not expect to be bored. And hopefully, after this outbreak settles down, and it's okay to be out and about without restriction, THEN the super-vacations can start.
