@OneMorePackPls asks
I made a dumb collecting purchase this year. How do I learn from it without replaying it forever?
Jeff answers
I'd write down the missed detail and one change you'll make next time, such as checking the language or setting a spending limit before browsing. Then let that action carry the lesson. You don't need to keep punishing yourself for the information once you've put it to use.
