So a lot of the time you see millionaires and billionairs on shows trying to guess the cost of stuff and going majorly out with their guesses (either two high or too low or it's just an arbitrary guess). But from what I've noticed, most people don't keep track of how much money they have, how much they're spending and how much they need...
That's why those people are not millionaires. Poor spending habits are very common, people don't look for better deals, don't bargain, don't control themselves, don't invest money and then wonder why they are so broke.
Quite right. The truth is that financial management is an alien thing to many of the poor. I am not sure if the rich are good at it. I have no idea. What I know for sure is that the rich doesn't have to care whether a cheaper brand of laundry soap is as high quality as the more expensive one, or buying a 300 mL shampoo would actually save you a few dollars in the long run as compared to buying 100 mL every week or two. They need not bother about those things, but the poor surely must. Well, at least if they want to maximize the limited money they have.
