I want to stop wanting MORE

Hi. I’ve noticed recently that I’m not happy with the great life I have and am always wanting more and more… a bigger house, a nicer car, etc. We have a great house, but I struggle to enjoy it because the other houses on my street are bigger and nicer. I want to move away from that and learn to be content with what I have. I don’t want to chase happiness but to feel content with “enough.” Are there any books to help me learn and choose to be content with enough instead of feeling down that other people have more? This thing has plagued me for years and I’m ready to make some changes. Any book suggestions on where to start? Thank you!
