There are two types of money: solid and liquid. Poor people knows only the first type.
With me it is funny because I still have the genetic traits from my poor family, and feel pain if I spend 20 bucks on something nor worthy the value, but dont feel anything if I pay 20 in fees for a crypto transaction. With this contrast I learned there are two kinds of money. Learning to isolate these types is the first step to win over family habits.
