book yourself an adventure to distant lands exclusively by yourself. the further, the better. take lots of photos, meet lots of people, and break lots of your own personal rules. i'd like to suggest the beautiful city of amsterdam as the location of your solo adventure. it's clean, friendly and full of activities. if you aren't very resourceful, are a little bit shy, or unwilling to try something new, then you'll probably have a really, really bad time. don't die!
