I’ve always believed in “no regrets”.
What that has meant to me is not regretting your choices in life. Whatever the choice you made, your life could have been better or worse, since you will never know, there is no sense in regretting it. Every choice I have made in my life has led to me where I am now. For example, I would never change, or wish to change, a choice that would mean I don’t have my two beautiful children. So, I have no regrets.
The realization that I came to, is that there is another side to “no regrets” and that is actively making decisions. Do I do this or don’t I? Do I do it now or wait til “a better time”? Which choice might leave you wishing that you had done it differently? I’ve found that my own life experiences (YMMV) have shown that doing it or doing it now, even if they were poor choices, left me with no regrets. I tried, I took a chance. It has always turned out better than being afraid.
