People who lack a sense of where to spend money will not succeed.

I don't spend money on slightly expensive things like UberEats, but you should invest in information even if it's a bit more expensive. The more capable you are of earning through investments, the less you'll struggle. Sometimes just by spending money, great ideas can emerge, leading to earnings of millions or tens of millions of yen. Instead of being stingy in strange ways, quickly elevate yourself to higher levels and you'll see quicker progress in life and higher happiness. It's a common problem that too many people misuse their money. Oh, and that doesn't mean you should buy strange investment information like some kind of fishing scheme.
