Most of my clients this week had a theme of being stuck in regret. And I laughed to myself because I was actually in the middle of doing the same round of work on myself that I was asking them to do. Since I was so raw in this area, I was even more able to help than usual.
Keep in mind that good decision making is acknowledging a mistake, learning from it, and making life better in the future. Don't spend your life reviewing past mistakes while the world goes by.
Everyone has regrets. Historical is hysterical. It's easy to look back at the past now and see the road signs we missed. The forks in the road we could've taken. Those forks are regrets. Is it bad to look back? Of course not.
