My desktop disaster!

I have got so many things here and there, my sister has been complaining and asks me to clean up. I am trying to do so but I find that everything is needed. My desk is not good looking at all, there are papers that I have not file up.

I know I need to get it off my desk, I need a clean space to work. Maybe I should get myself an utilize shelf but I do not like it at all. I love everything that I have got on my desk.
