Traveling alone is one of the richest experiences I have ever done. I am really fan of traveling alone. I don't care the destination, the conveyance or how long is the trip. I have always thought the trip begins when you leave your home, not when you arrive to the destination you are going to, and the time you spend at train stations, taking buses or dealing with other travellers, is a great trial to know how you can manage yourself when you are alone in unknown places surrounded of unknown people. Some trips are easier than others depending the country or the culture you are visiting, but the compulsory use of other languages to make you understand, and be able to solve the problems you find when you are alone, is a fantastic proof to put into practice in your daily life.
