I think one of the most important things people should consider when discussing or deciding to improve your privacy is to first define your threat model. In other words, what is it you want to protect exactly? What are you worried about? Because there are some things that just can’t be done realistically, or things one person might take as a requirement that really doesn’t matter to the next person, sometimes for surprising reasons.

For example if you’re worried about three letter agencies doing something, well, sorry to say but you’re probably screwed if you’re reading this.

If you want to be able to browse online 100% anonymously, that’s also extremely difficult (and some say impossible, cough creepjs) even for the smartest people.

If you’re worried about companies and advertisers selling your data, I think there’s a lot more you can do to mitigate this than the above things. But some will still argue even going outside at all, having a job, or spending money on things can be a big threat to that too.

Basically decide on what things you actually care about, and start there vs just reading randomdude.com’s “subjective guide to privacy 101”.
