Did you notice that a male and a female voice differentiate the train station announcement between uptown and downtown train? Because I already had recognized this differentiation, I had an experience that I did not miss the train. Since then, I have been asking many people who were using the same train station if they noticed about this differentiation, but no one knew about it. 


In a daily life and at work, there are people who could discover the difference or not. And you may claim that those kinds of small details has no importance and can be ignored. But I truly believe that people who could discover those things will make a big difference in a whole life and work.


And then, how can we discover those things? Of course there might already be an individual difference at birth. But what I think most important is that we maintain  “curiosity” like a child, increase “sensitivity” about anything, and also have some “room” in your mind as well.
