As I read today's nikkei evening newspaper, it featured mindfullness.(We recently see this topics in many media)
And this article said that one method to boost one's concentration is to shut down various informations from our eyes and ears. That's is what I often thought.
There are so many informations around us and we can touch many informations from ubiquitas it mobile. Especially SNS are such media. These are designed to stimulate one's curiosity. And recently I strongly think that these things consume our time so getting away of these things is very important skill for us, I think.
