Daily jogging, healthy diet, and meditation make the biggest difference to me.
The biggest change I'd like to make would be to defeat my social media and entertainment addiction - not even entirely, just contain it to a 2-hour window every evening. I keep failing at that, but there were weeks/months when I was successful, and it made an enormous difference, way more than I expected.
I switched to mac after about 10 years on linux, and I'm not going back.
I'm also very annoyed by most of the things you have listed, but there are two things that are a deciding factor in favor of mac for me:
1. In addition to webdev I sometimes need to do design, graphics, 3D art, and on linux most of the software just doesn't work. There's absolutely zero chance I'd be willing to cope with GIMP and Inkscape instead of using Photoshop and Affinity designer. There's a lot of other software (for screen recording and video editing, for instance), that works on mac and doesn't on linux.
2. On mac, things just work. On linux there's more customization, and open source software, but you pay for it dearly by having to spend hours (sometimes days) tinkering with configs and installing dependencies every time you're trying to get anything to work. I didn't mind that before, but at this point, I'm too old for this sh*t. I just want my laptop to work and help me do my work and make stuff, I don't want to cross my fingers and pray every time I need to install something I need to get anything done.
That's a big part of the problem - a group of people have unilaterally decided that they're the grown up ones, and they know better, and dismiss everyone else as toddlers.
Using that wonderful justification, they proceeded to censor everyone who disagrees with them, including the points of view that later turned out to be correct.
When you decide that you're a smart adult, declare every dissenting viewpoint to be "disinformation", and, therefore, you get to decide for other people what they do or do not get to read or think, and then you get it wrong, people will be justifiably upset. Even if you get it right, people will be upset.
So here's a wild suggestion - why not treat other human beings as adults capable of making up their own minds about things?
