I'm not ashamed to admit that I screw up sometimes. But I must also admit, I'm not always super quick on the draw to take responsibility for my errors, omissions, mistakes, or misdeeds.
I generally spend a bit of time thinking through how something is more your fault, or their fault, or anybody else's fault but mine. It's not fun to admit when I mess up.
Unfortunately, owning my mistakes is the only pathway I know to releasing them. So I eventually exhaust the blame game and find my way into what is truer—that because I am human I made a mistake.
I have to embrace the icky feelings that come along with screwing up, but then I claim the screwup and figure out how to get to the other side of it. Not everything can be fixed, but I can apologize for everything and try to avoid making the mistake again.
And then I can move on. Life can be messy for us humans, and mistakes are a part of it.
