What really bad purchasing decision have you made? and were you able to fix your mistake, or did you just have to live with your regrets?
To be really bad, it also has to be fairly big. How big is that? Big enough that you couldn’t just afford to ditch the poor choice and buy another whatever-it-was.
Whether that’s on the scale of a car for you or a pair of shoes, a TV or a house, the point is that it was an expensive and painful error.
