first you need to realize that the cultural phenomenon where a man's status is determined by what he owns is a jewish construct promoted to keep you enslaved because you never have enough. after you realize that, it becomes very easy to adopt a more minimalist lifestyle and reject consumerism. and once you do that, you realize that you don't need that much money to get by and you start saving a lot. if you invest those savings wisely, you can retire early, and the fact that you don't care about materialism helps you reach retirement faster too because you need less to retire.
