Trying to protect everything from everyone all the time is a good way to drive yourself crazy. This is why we threat model. Here is EFF's Surveillance Self Defense guide to putting together your security plan, also known as threat modeling: https://ssd.eff.org/module/your-security-plan
Your Security Plan

Trying to protect all your data from everything all the time is impractical and exhausting. But, have no fear! Security is a process, and through thoughtful planning, you can put together a plan that’s best for you. Security isn’t just about the tools you use or the software you download....

@evacide This is a well structured intro to threat modeling, which is a more pragmatic way to handle security than the more typical anti-patterns of fear mongering and security theater.

(Plug) A while ago I wrote this guide on applying threat modeling to protect your mental and cognitive health in the age of social networks. I think it's still very relevant.
