The best way to live with no regrets isn’t to pretend that past actions don’t bother you. The best way to live with no regrets is to not do regrettable things.
How can we accomplish that?
By thinking ahead. By thinking before we act.
[Trite advice like this is exactly what we need sometimes. To quote Charlie Munger, “if it’s trite it’s right.” The truth is we often don’t put enough thought into things before we act. We often don’t realistically weigh the consequences of our decisions.]
