I like this quote a lot:
People who give themselves feedback in the same heartless tone. They don’t hesitate to brutally lash out, because that’s the noise they often hear inside. – Harsh feedback | Seth’s Blog
I find it to be true.
I tend to do this quite a lot.
Sometimes, I give myself harsh feedback, and, at times, I put a mirror in front of others’ eyes.
I do my best to avoid this, lately.
