Put away all the backwards looking shit and move forwards. Cycles should end – they need to be let drop. Even if you don’t think the person got their needed comeuppance, once you have done what you can to ensure that happens, exit the cul-de-sac and leave them to their own dead end, if that is where they wish to stay.
No one else reflects on you, and it helps you not to look to them to be your mirror.
Are you happy with what you yourself are doing? Do those around you feel that you add to their lives? Creativity and ethics, and everything else is all assessed on a personal basis. I am happy where I am and where I am going. What I have been and what I have done are gone, though the worm casts remain. I do not try to erase or rewrite the past as being horrible or something to regret … it just was. Everyone has responsibility for their part in that, and in the future going forward.
