I don't usually seek self help books, but I'd love recommendations, if you have any, on books that helped you stop overthinking, expect less from people, base your happiness and focus less on others, have self confidence and sufficiency.
I've heard of books like Ego is the Enemy, Never Split the Difference, the Happiness Advantage, but I haven't made up my mind on one to start on (part of my problem perhaps haha)
