I think it is a bit of a limbo time.
As I have written on here before, we went semi retirement. But now started another business as DH got bored.
DH and I are not one for many hobbies either. I rather wish we were, but never mind.
We both volunteer which helps a bit.
I probably have two suggestions. [I am no expert].
Yes, work out your finances. You will need to know where you stand with your new ingoings and outgoings, figures.
Also, having been on the forum a year, I think I have seen a thread or two about retirement. I will see later if I can find them.
