Agreed. I also grew up poor and now live comfortably. Having my own place with no roommates (or mentally ill family members screaming at me) brings me a lot of peace. Being able to just uber somewhere when I have an appointment but feel too tired to take public transit for 45 minutes makes my life easier. There are a lot of problems in life that you can make disappear (or simplify a lot) by throwing a little money at them. You can remove a lot of stress factors. Money gives you more freedom to choose what you want your life to be like.
The flipside is that I know very well that, if I'm in an anxious mindset, my brain will find things to worry and be unhappy about. I know being a multi-millionaire wouldn't bring me bliss, but... Being able to work on my own projects, as much as I want, whenever I want. That would be fucking awesome.
