Yeah for sure, you don't need to consume to be happy. That is a failure and false happiness that depends on external things. It's always seeking more through consuming.

Indeed, gaining satisfaction helping others, is much better than gaining satisfactions from having purchased something, and then you get bored with it or whatever and look for the next thing to buy to give you some sense of completeness. Helping people evolve and overcome problems comes and goes, but you have lasting impression that lasts your whole life in terms of uplifting someone and yourself and it permanently affects your consciousness and state of being. Buying things is just a fleeting false completeness, but when you affect your core being it lasts forever.

Take care. Peace. Upvoted.
