It’s not easy to accept something unacceptable.
It’s not giving up, its just your way of working, the one way of working doesn’t work.
And it falls under “I am wrong.” Maybe you should have done due diligence, maybe you should have worked harder. There are a lot of “may be’s.”
Why can’t it be simply “I am wrong” and move on?
Why “I am right” is stronger, may be because the stakes are higher, may be because people are around.
Yet, as humans, we’ve come this far because of many “I am wrong”s and far fewer “I am right”s. So, let’s keep making mistakes and keep accepting them.
