I often head into the city by myself to have lunch by myself. I find it very relaxing to have a stroll with my own thoughts and to do some reading during lunch. I can really recommend it.

One of the most exhilarating things you can do is travel alone. Travel wide, and far - another country - entirely alone. Stay in hostels and force yourself to make friends. Be who you want to be. Do what you want to do, when you want to do it. You learn a lot about yourself when traveling solo.

Why not a person rating system - OkCupid for friends? Pump in your interests, get matched, and peer review the experience. Tongue only partially in cheek.
