So far adulthood is just going grocery shopping, realizing you didn’t plan well or logically, going grocery shopping again, repeat ad infinitum. 0/10 stars, would not recommend

make a list. then ignore the list. stop 5 or 6 times in the middle of shopping to estimate your purchases. Put things back. look morosely at your wallet. Realize that the wallet is you, without it you are half of nothing.
