The boring but truthful answers of “I have bills that can easily soak it all up without an issue (mortgage, student loans, car, etc)” have been said, so assuming I cannot use it to repay any debts, and I have to make actual new purchases, I’d buy things that I could pay for now but enjoy for a long time. 3-year VPN plan, multi-year phone plan, gift cards to restaurants (especially with a bulk discount like at a Costco), etc. Upgrade my cockatiels to a cage that goes wall to wall with real plants hanging out and all that. The little things that cost enough that I don’t get them but not enough to be a life-changer. Probably be a good amount left, I’d get a moped or electric bike of some kind, and I’d upgrade my laptop to a stupid powerful one.
Worth a reminder that *'s get converted to italics. At first I saw the 2+58-55 and was very concerned for your education.
