Do you know what is toughest thing in the world? You must be thinking that toughest thing can be rock climbing, walking on rope or living without food and water. These things are tough but, as i think the toughest thing is to "pass free time". Everyone has different way to spend their free time. When I was little chap i.e. i was around fourteen I use to spend lot of time with my pals, and I was used to watch music videos on my television.
