1) Try to be very careful — traveling is dangerous sometimes... 2) Follow the rules of place you are in and listen to others. 3) Be polite and do not do rude things to others. 4) Smile and keep positive — people love persons with good mood. 5) Take a camera with yourself when you are going to any place. 6) Visit places you want to visit. 7) Enjoy while traveling!
