Makes me wonder, many people do follow the knowledge/wisdom step, but 1% only manages to get wealthy out of it. Most people just jump over it and merely get the self-improvement part per se. As wisdom/knowledge = self-improement = spirituality basically. Even lifting weights, as said by some enlightened dude from india, is a "lazy mans way" to achieve enlightenment. When you tense your muscules and focus for one last push, that's the meditation you go through.
