So many options

I find reading philosophy in general to be better self-help than these actual new age self-help books. Taoism is particularly relevant today because of cult of productivity, utility and hustle culture which I find rather surprising people are doing-- because this trend is only serving the capital owners at the end, not yourself. Taoism teaches to slow down and at times being "useless" proves to be more useful.

Excellent depiction of the capitalism-ism of mental health.

Turns out they are all the same book, and that book is bullshit

Idk who said it but self help comes down to that ancient greek philosophers axiom "Know yourself." Know your emotions, your past, your behaviour, motivations, desires, relationship style, socialisacion your dispositions, strengths and wounds. That is the foundation for all really. Get to know yourself. Self exploration can give your life meaning.
