The effect of asceticism (avoiding indulgence/extravagance) is that you do not want for anything. Anything material.
For little changes you.
$800,000 per year income, or $40,000 per income, and you act the same.
The only reason to act markedly different in this example is in pursuit of status.
Asceticism is a form of Essentialism – I think.
To understand the liberating effect of asceticism, consider that losing all your fortune is much less painful than losing only half of it.
