the few days before you go on your trip is always nerve racking for me. i always think to myself "am i making the right move" or "why am i doing this" and of corse "what if something happenes to me or my family while im away". honestly i havent figured out a trick to rid myself of cold feet. other than reading and researching places to see and go.
but once i walk on the plane somehow i become clam and all my worries drift away like the like the landscape beneath you. after you land at your destination you'll havev nothing to worry about except where you will go next.
