Some stuff I didn’t see in reading responses.

• Learn some “handy” skills. Create, build, repair. Stuff breaks all the time (and is probably only going to get worse), and as an adult you may be the one responsible to resolve that. It’s satisfying to do, saves money, makes you more independent, and might even open additional employment avenues.
• Do travel. Pick places with cultures you aren’t familiar with. While some high costs may be unavoidable (plane tickets, for example) travel can generally be done fairly cheaply. It’s an amazing experience and I think can give you some valuable perspectives on life.
• Be reliable. Having a reputation of someone who does what they say they will may open doors.

Something I did see but wanted to say as well anyway:

Don’t try so hard figuring your life out that you forget to live your life. Find balance.

I’ve been meaning to try out meshcore, but haven’t gotten around to it. It does sound promising.

In that it’s a mesh network deployed and controlled by individuals, and provides a level of encryption, yes.

But the limited range and low bandwidth makes it ineffective at a large scale. Also a nefarious party (the government presumably in this example) could determine the rough location of nodes, were they so inclined.
