Don't save the money you have left after you spend it;
spend the money you save.
Income - Savings = Consumption
This may sound convoluted, but it's the watershed between rich and poor thinking:
‼️The "Moonlight Trap": Income - Consumption = Savings.
The result is that desires are never satisfied, and savings are almost zero.
The Buffett Model: Income - Savings/Investment = Consumption.
The result is that you first secure the capital to "make money work for you," and only then can you spend the money you have.
