Oh my goodness. How do you pack a life into 3 suitcases? Editing has never been my forte. Editing has never been a gift that either of us possess. Amazingly enough, trips are one of the things that allows us to edit pretty well. There is a clearly defined period of time for which to plan. There are specific places to visit. There's not a lot of time to waste. You don't get bored. The only plan is a short term plan. What a relief! However, 4 months is verging on the long term, hence my trepidation. I guess if I think of it as 2 two month trips, it will seem less indeterminate. Still have to pack those suitcases, though.
Another thing about leaving a life behind, even for a few days, is the feeling of a fresh start, a life unencumbered by the routine and "stuff" in our lives. Instead of wondering what to keep, what to save and what to give away, you just leave your stuff. Kind of like dying, except you get to come back. The same thing goes for worries. Either you took care of them the best you could, you don't have time to think about them, there's nothing you can do about them, or they don't matter as much as you thought they did.
So if you don't have your stuff and you don't have your worries, what is left? Adventure, I hope. And probably new stuff.
Well, I better get back to packing.
