I know what you mean, and you didn't even mention the thing that makes it extra stressful: The fact that other people keep doing all that stuff anyway. So you either disadvantage yourself against them while having no real effect as an individual, or you do the same as them while always feeling bad about it.

Although some of those things don't necessarily make life better anyway. Sometimes I'm happier having a break at home vs. trying to plan a vacation, and new gadgets often just mean more work in your life to maintain them. Not to mention the extra work you have to do to afford it all, that you could instead have as free time.

But in the end, I think individual change on a large scale requires government legislation, and government legislation requires worldwide agreement, because no-one wants to be disadvantaged against everyone else. Tragedy of the commons. But we do what we can.
