Replying to Travelling alone

has anyone ever done it? I plan on hopping on a plane in june 3000 miles away and surfing/working for three months all by myself. i think half of the allure of me doing it is the fact that ill be alone, and that everyone thinks its a scary thing to do. Ive never been, and dont know anyone there, i kind of just want to make my own way. i was just curious if anyone has ever done an extended trip alone and if they had some insights or advice or stories to share.
