When your destination is about to arrive, just be ready with your bags and count all the items. Most of the people do this mistake and they often miss their belongings in the bus.
Keep good collection of your favourite songs in your cell phone or mp3 player. Also do not forget to carry your earphone with you.
Bus journey gets more comfortable in large groups because you spend your time in talking to your known ones. Hence if possible try to get people along with you during bus journey.
