In the song Sweat Loaf by The Butthole Surfer's, it is posited that it's better to regret something you've done than something that you haven't done. Is there evidence to support this claim? I feel like most people regret the things that they didn't do more than theThings that they did. Mostly because there's no counterfactual. You can't go back and fix it. Well, there's always a counterfactual,. The counterfactual, in a sense, is the road not taken or the road's not taken.
