I guess it depends on how much money you're talking about?
I mean is this like a full salary, so you don't have to work, but you do still have to be careful?
I guess, if I received a full salary, I'd probably still keep working for a while, I'd do that so that I could save up more money to actually buy a house rather than rent, I might cut down my hours so that I only had a part time job to make sure that I didn't just sit about doing nothing.
I'd have a home workshop and I'd build and fix stuff in it.
