Lost lessons.
I’ve lost jobs, friends, money, illusions, dogs, contests, self-confidence and relatives.
The lessons seem to be similar, regardless of the details.
If you wished you had done more, tried harder, or reached out to connect, do so going forward.
Own the responsibility and don’t repeat the behavior.
Take time to remember and revel in the good parts. There are always good parts.
Unexpected people show up, some you expected show up, some you thought would, don’t. Appreciate the former, love the middle (rocks), and forgive the latter.
It’s the past. Learn. Make new relationships. You will make new mistakes, don’t repeat the old ones.
