I am a big fan of this. As a 25 year old, I feel that I was truly the last general to experience what true boredom was like as a kid. Hanging out at the school during the weekend wondering what to do - those days are over now. Technology has definitely taken over our lives, and now there's always something to do.
I believe that leisure time is something that most people don't have nor know that they want. As the article states, it lets you think outside of the box and come back with fresh ideas. In a work-centered society though, it's really hard to justify spending that time. Even knowing all this, I still fall into the trap of always being busy with something.
