If you want to keep your sanity as an expat, get out of country at least once year. More is even better.

I have lived overseas in Japan for more than 20 years. I have a rule for myself about leaving the country at least once a year. I broke that rule this past year and noticed that I was getting stressed out and feeling stuck. 

I just took a week long trip to visit some friends in Sweden and I feel a lot better. I have a much better perspective on just about everything, including what I need to do to move forward in my life.  And spending time with good friends as great for the soul. 

Even if you aren't an expat, travel overseas at least once a year. The world is such an amazing place. Just do it. LIfe is short. Standing in a land with a different culture and different smells is a really good reality check.
