In the United States of America, there are over 500,000 people that work in the diet and fitness industry. The funny thing about that is the fact that almost all of the advice concerning health could boil down to one sentence: either “exercise more and eat less” or “consume fewer calories than you expend.” Everything else is a derivation or a specific look at that principle. The entire industry is built upon a permutation of that principle.
Personal finance and investing is much the same way. Even though it is a crowded space (I can only imagine how many finance writers and investing advisors exist in the United States alone), the message is not terribly complex. A successful financial life all boils down to one thing: spend less than you earn, and do something intelligent with that surplus. My website is dedicated to advocacy of documenting why high-quality blue chips can be the intelligent thing to do with that surplus.
