Have you personally overcome imposter syndrome through this advice? Because it sounds to me like a theoretical take, not one that has been well tested.

The people I know who are or have been overly self critical are not lacking in "objective facts". They have been damaged by dealing extensively with people who are overly critical, often to the point of emotional abuse. So they have problems with selecting which facts to focus on and how to weight them emotionally. These are often not conscious problems, and so getting out of them doesn't just require rational-mind realizations, but changing deep habits of thought.

I also am very concerned about this, which I think is potentially harmful to some people, especially those struggling with self esteem:

> For most of us, to love ourselves means we should be aspiring to something better, and not content with how we are now.

I think this could easily be read as meaning that aspiration is a precondition of self love. For people who have been told from their earliest memories that they are inadequate, tying self-love to self-improvement puts them on a treadmill that never stops. Love does not require improvement or perfection.
