Are you a jack (or jill) of all trades?
What are you good at? What do you know how to do? One thing I have found to be invaluable to being more independent and self sufficient is knowing how to do things.
I’m talking about being a jack of all trades, someone who can do most anything, and the things you don’t know how to do, you should be able to figure it out enough to get by, or at the very least, have enough other skills to trade/barter with someone else who can do that one thing you can’t.
