If you never repeat the mistake how could you regret the experience?
Yes it was agony to learn that lesson the hard way but think of all the pain saved!
Pain experienced is visceral but pain avoided is often ignored.
It’s hard to quantify all the suffering missed, we usually just adjust our thresholds to tolerate less suffering and move on. So taking a second is great for putting that mistake into perspective.
The torture of the past now ensures you leave a job before it becomes unbearable or pick the right partners for relationships or drink responsibly or drive safely.
If the mistake creates a better person, can it be regretted?
