Materialism

I'm not a religious man, but we'd all do well to reject extravagance because it doesn't make us happy.

We are livin, in a material world.
.. and I’m a a a a.. material gurl

speak for yourself, I like my possessions :p

You are right! Apparently they've conducted studies on this and found that actually things and wealth don't make us happy. Sure being poor sucks but once you have a certain amount, having more doesn't increase your happiness.
People, relationships, experiences etc are more likely to make us happy than material stuff

Exactly. Many people don't realize this until very late in life.

You need to find yourself. Develop hobbies and do what you love, love what you do

It must be nice to feel that way.

Yep. Learn and adapt. What do you need instead?

That's the lack of spirituality you're feeling. No material goods can fill that hole.
