Based on your question, you might dig the book “Boat of a Million Years.” The author put quite a bit of thought into just that.

I was not born into wealth, and put myself through college on scholarships. The only reason I’m “wealthy” is because I’ve lived very frugally (and still do), and chose not to have kids. I’m not denying that I’ve had some advantages, and certainly those born into the current economy have it tougher, but overall I’ve eaten a hell of a lot of lentils, don’t subscribe to any streaming services, am not much of a consumer, and enjoy the simple things in life. Obviously not an exhaustive list, but stuff like that. It’s not for everyone, but I’m deeply content and fulfilled.

Joyful, peaceful, content, fulfilled, educated, energetic, with a diverse set of wonderful friends, and a fun, flexible lifestyle. I retired early and wake up every day (whenever I feel like waking up) in a place I love. I laugh a lot and have a close “chosen family” who always has each other’s back. I wouldn’t trade it for the world.

The Daily Stoic by Ryan Holiday is a great beginner sampler, and/or a way to keep it in your life when you don’t have an appetite for the “heavy” stuff.

Especially in news headlines: slams, blasts, mind-blowing, hack (or lifehack)

I’m sure there are others, but that’s all my brain can handle at the moment.
