Kind of agree and also kind of disagree. For some things there actually are recipes. For instance, I greatly benefited from learning GTD (getting things done) at some point. Not having any sort of overview of all the things going on in my life was causing me quite a bit of distress.

Furthermore, I think it is good to have experienced multiple mindsets so one is not married to any single one of them. The self-improvement mindset can be one of the mindsets that one has experienced.
