That’s common philosophy. Only the most materialistic philosophy like consumerism will promote the never-ending pursuit of acquisition or achievement to happyness.

That’s the problem of our western societies in fact: they promote the never-ending pursuit of success, wealth, or fame. To actually be happy, you “merely” need to get out of this culture.

Still, and although some people can be happy with almost nothing, most people will still need basic needs fulfilled to be happy : food, home, and socialisation (and safety).
