I think the mantras above might be important for a person who struggles with criticising things they can't change about themselves, height, beauty, hair loss, age, that sort of thing.

I agree that it comes across defeatist using these mantras in relation to things you can change, like skills, outlook, fitness, number and/or quality of relationships.

Great distinction. I agree 100%.

Squaring the circle here: I love and accept myself right now, with all the flaws I know I have. I'm trying to improve, but who knows what I will and won't ultimately fix. Maybe this old lump of coal never will be a diamond. But I'm not going to wait til I've climbed the asymptote to start loving myself, I can just love the self I'm stuck with here and now.
