Some slow travel for a while to find a culture we'd like to settle down in. Eventually, find some land and do some hobby homesteading.
We both want to do some side gigs, more to do things we love than for money. I want to teach flying to keep up in the air (I'm a "pilot" now, but in the military that ends up practically becoming a side gig in itself as you gain rank). I also love cooking, and I'm thinking of getting my feet wet trying the chef thing somewhere. My wife is very artistic, so she'll probably focus on that (actually sell some work instead of just donating it) and she's expressed an interest in becoming a tattoo artist.
Many other options have been thrown out too. The general idea is that we eventually want to buy some land and build a house. In that vein, I plan on picking up several trade jobs over the years to learn housing skills to a more competent level. Plumbing, electrical, general building, etc. I've done some volunteering for habituate for humanity for that same reason (trade my time for learning some skills), but after we retire that will be much more of a focus.
So, with that rambling all done, basically the point is we have many paths we want to pursue, and lots of time to do it. In the end though, this will probably amount to my family saying, "You quit your career to become a burger flipper? WTF is wrong with you!"
Eh, only so much you can do. ;)
