90min.

 That is the time I need to come to school. I am coming from Yokohama by taking 3 different trains and a bus to get to the school. It's pretty long compare with other students who live in Tokyo, but it is not as long as some people think. I know some of my friends who is coming to the school from Chiba and Saitama, and I heard that there are people who use bullet train everyday to get to the school. So I think 90 min is not that long and I can actually enjoy my time on the train by doing different things. One thing I do most frequently is reading. I read newspapers, reading assignments, and other books I rent. At first it was difficult for me to read on a clouded train, especially the newspapers, but now I got some skills which enable me to do readings on the train. For example, if you want to read without wearing out your shoulder or legs, one thing you should do is to get a space on the overhead lack and put your bags as fast as possible before a business man who stands next to you puts his business case on the space. You might think it is a little thing, but it actually makes a big difference. I know this from my numerous experiences, so you can count on me that. The next skill is to have different kinds of reading. When there is some space around you or if you are lucky enough to get a seat, you will have no problem with reading news papers on the train. However, when it is clouded, you might don't want to read newspaper and to make noisy sounds by flipping the pages. Otherwise, you will make people around you who are already grumpy and tired more grumpy. So I think when in such situation, it is better to switch your newspapers to a novel or other smaller reading materials. Or if you desperately want to read the newspaper, you should get an i phone because now all the international papers are available on online and you can even watch news programs on your smart phone.
 When I get bored with reading, the next option I have is to watch videos on my i phone to study languages. I often use youtube to watch different news programs, interviews, and other TV shows in English to advance my listening skills and to learn new vocabs. Also, I often watch TED on youtube. On TED, you can watch lectures by scholars and professors from different fields and some topics are really interesting and stimulating. Most of the languages are spoken in formal ways, so I think it is a good way to study academic English. Also, topics which are discussed on TED are current and something meaningful, so it is good not only for language learning but also for learning in general. 
 There are of course times when I do not feel like doing anything productive, so in these times I just listen to music and try to kill the time. However, recently I realized that even when I am dead tired and do not want to do anything, if I have to spend the same amount of battery of my i phone and 180min of my lifetime, it is wiser to listen to some academic lectures rather than just listening to music.
