Overview needed

Thank you in advance for help with these questions.

I’m completely new, except for a false start on another site a few years ago. I’m more motivated now, exploring which skill sets will fit best with my values. I am for privacy and free speech, and for working remotely in order to travel. Suggestions for a path that will accommodate these values?

According to TED talks on learning how to learn, anyone starting out needs an overview understanding of the topic in order to see how the pieces fit together. Suggestions for where to find this? A visual would seemingly help. Thank you!
