Every life is the compounding result of decisions made using imperfect misconcepts. Improve the misconcepts behind those decisions, and everything that follows improves. A life trajectory changes not through a single dramatic choice, but through billions of ordinary ones made with better misconcepts.
For you
To get the highest return from your finite life resources by building fit-for-purpose misconcepts and making better opportunity cost decisions given your own arbitrary life goals. By doing so, you compound towards your own definition of a good life.
For society
By helping individuals make better decisions, demand shifts away from status signalling and exploited cognitive defaults towards genuine value. Markets adapt, allowing resources to flow towards solving better problems, which in turn leads to better outcomes for both individuals and society at large.
