Some things to read:

Dave Ramsey has a podcast and many books, and while he mostly talks about getting out of debt, he’s really talking about controlling your money.

Look up asceticism. I don’t think it’s the answer but it has a lot of helpful things to say, particularly imo Christian asceticism. Stoicism might be similarly helpful: not the answer but says some helpful things.

I wholeheartedly agree with the others who say to limit your exposure to advertising. Over 10 years ago I drastically reduced my TV watching and that alone has helped tremendously.

Spend time with people who have very little, such as people who are homeless. It helped me to gain a different perspective.
