I shouldn't be too hard on myself? gee thanks, a fortune cookie can tell me that. And it's a shorter read too.
Why does the obvious question go unacknowledged by this article? The question is roughly "How does someone calibrate how they reflect on their actions and effectively guide themselves through life?" People are not tough on themselves for no reason, it's a (possibly misguided) attempt to push themselves towards their goals. If you tell them to be self-compassionate without answering that you're setting them up to resist your advice.
What deduction am I to make other than: the article doesn't address the question because it doesn't have an answer.
NB: I have an answer that works for me; I'm talking about how good this piece of persuasive writing is at providing one for people that don't. But thanks for the advice.
