Can there be a more useless emotion than regret? Trust me, I’ve made plenty of stupid mistakes and bad decisions in my life, but I don’t regret any of them. They were what I chose to do at the time, and represented the best decision I was capable of making in whatever state of mind I happened to be in at the time.
I mean, seriously – what does regretting do that serves any purpose at all? Reflection, on the other hand – very useful. Regret – a total waste of time and energy. Apologize if needed and move the fuck on…
