This is hard.

I try to remind myself that I did what I knew at the time, what I thought best, given what I knew then. And now that I know better, I do better.

I also try to remember that the most well rounded people, have not lived a life without regret, or hardship, or mistakes. That we learn best from mistakes and poor decisions and that those regretful decisions I've made, have helped me too in some way.
