I am aware that this is not a new revelation and I'm not going to pretend to be an expert on this, nor am I a purist when it comes to consuming. I'm not claiming I don't participate in the capitalist regime at all. It is almost unavoidable in. But I do know from personal experience, how stressful, overwhelming and quite honestly soul destroying it can be to constantly spend my hard earned cash on objects of empty promises.
Whether it's clothes, cosmetics, furniture, computers, appliances or even excess food, buying too much only leaves you with an overwhelmingly full house and an empty wallet. My life and mental health improved exponentially after I made the conscious decision to not only stop mindlessly seeking more stuff to own, but actively ridding my house of excess and adjusting my working hours and budget accordingly. One book that helped me do this was Marie Kondo's "The Life Changing Magic of Tidying Up". Theres a really great blog post from One Kings Lane about her experience with the KonMari Method which pretty much sums up what I experienced too (minus the part where a ridiculously cute toddler distracted me for an afternoon). Basically less IS more. It is better for the world, and better for your brain to consume less.
Some other people experts on this are Joshua Fields Millburn and Ryan Nicodemus of The Minimalists. Rather that list some "hot tips" for living minimally, I'm just going to direct you to this blog. These guys have it covered.
