It isn't a euphemism, it's about being kind to myself. Literally.
See, i have to make a huge effort to consciously tell myself I have done well. I have to drown out the subconscious, insipid, nasty inner monologue that tells me I'm no good, that no one wants/ likes/ cares/ listens.
It takes a lot of effort to tell myself positive truths. It's easier to not do that. Short term anyway.
It's a big thing, this self-compassion. Maybe, one day the kindness will be the subconscious autocue. I'm sure it will, practise makes perfect.
