I just got back a month-long trip by myself. It was interesting to note that a ton of people I talked to before going, friends, family, acquaintances, were all shocked I would travel alone. The overwhelming response was, "aren't you going to get lonely?" I think it's important to be alone and enjoy your own company.

Working remotely too, I get a very similar question. "Don't you miss working with people?" I work with people all the time, but I think that being alone magnifies the effect of spending quality time with people, rather than just spending time together for the sake of being together.
