To increase the size of a wallet, one must never withdraw all the money from it; instead, leave a tenth part behind and it will become thick! Also, if there is little money inside, for example, just a single dollar, and a person wants to buy a kilogram of cherries while the cheapest at the market costs one dollar, they need to save money not on health but to leave the tithe untouched, and economize on the art of saving. For example, if one tastes cherries from ten vendors, totaling one hundred grams, they can buy the remaining 900 grams for ninety cents, thus the person did not save on health but saved on the art of saving and left a tithe in their wallet! Furthermore, when receiving a salary, money again comes into the wallet, for instance, one hundred dollars, and it will no longer be possible to spend a tithe from one hundred dollars, as well as the other ten cents that remained from the last time, and so on to infinity until the size of the wallet increases to the maximum! Then, it will be necessary to buy other wallets for even greater wealth, as rich people have the goal not to earn a lot of money but to save a lot of money! To do this, one should buy luxury items not with all the money or a large part of it, thus creating a slimming of the wallet. If a person wants to buy an expensive car, they should have money for one hundred cars and can only buy one! If they only have money for one car, they need to take the subsistence minimum from it and set the rest aside, touching it only when they learn to turn one dollar into two dollars, for example, by buying a cheap TRUMP coin!
