Make a checklist in advance for all the items which you would be carrying during the bus journey. Check this list prior to leaving your home to make sure that you have not missed any item.
Keep good collection of your favourite songs in your cell phone or mp3 player. Also do not forget to carry your earphone with you.
While getting down from bus at an intermediate bus stop, always ask the conductor about the break time and come back at your seat just two to three minutes before.
