1. Sit by a window. You have better control of temperature and it makes me feel superior to be the "window master"
2. ipod. Sometimes I'll read on a bus but a lot of times the roads suck making it impossible to focus. An ipod loaded with music, podcasts, and audio books is key. I also just got a headphone splitter so now me and 4 others can listen to the same ipod which is great for listening to comedy because other people on the bus get freaked out when a group of Americans are sitting in silence then suddenly all start laughing at the same time.
3. Sunglasses. Even in the winter. People talk about me right in front of me and have an intense desire to stare. Sunglasses let me stare back or fall asleep, two birds one stone.
4. Don't travel. I need to follow this rule better but being on buses in this country usually just makes me mad. I'm gonna start taking more trains.
