Travelling on your own is harder work than with company; you feel the good times and the bad times all the more because there is no one to share them with. You have to become emotionally self-reliant, calling fort reserves of physical and emotional energy to get you over the hills and through the inevitable hassles. (…) Solo travelling is therefore potentionally a lot more rewarding in terms of personal growth as well as the freedom you experience.
