I make the majority of my living from books, which means that my pay is very "lumpy" - I get large sums when I publish a book and very little in between. For many years, I've used these payments to make big purchases, rather than financing them over long periods where I can't predict my income. We've used my book payments to put in solar, then an induction stove, then a battery. We used one to buy out the lease on our EV.
