I’ve been a trainer and coach for many people over my 10+ year career and I’ve noticed that it seems that your words and thoughts dominate your reality. Now, I know you’re probably saying that this is woo-woo type stuff here, but hear me out brochacho.
The reason why we have regret is to learn a lesson. If we don’t learn the lesson, then we will continue to regret. You see, regret is simply a lesson that we have yet to learn. However, when you focus on the past, then you decrease your ability to impact your future. So it’s kind of a double-edged sword if you don’t deal with regret.
