What to Bring and What to Leave Behind

So, leaving for a foreign country for an indeterminate amount of time. Probably at least three months, potentially forever. How do you plan for that? What do I bring? That's not the hard question. What to leave behind? That's the problem.

Taking advice from people who know, I am getting rid of a lot of furniture. Happily, my family is interested in a good number of pieces I like. The only thing I'll need to put on Craig's List is my queen bed. The other furniture that will stay in storage are each pieces that come from my grandparents. Items that mean something to me. My maternal grandfather's desk and dining room table, my paternal grandparent's glass-topped table and reupholstered love seat (gift from my mom and dad). I want those ties to my past. The LLBean Kitchen set, not so important.
