How do you make commuting more bearable?

[Dark Sun]

Sure many of us do this and have to travel a few hours a day to and from work on the train. So how do you make commuting more bearable?

Noise cancelling headphones?
iPad?
Book?
Sleep?
Combination of the above?

Is anyone here one of those annoying gits who takes up three seats during rush hour with their bags? Then give a dirty look when asked to free up some space? Additionally, perhaps you like to mash a sandwich into the seat so no one can sit on it. If you are, I'm sending you a burst of negative energy.
