Jun 3th 2013 Life is amazing sometimes it is this, and sometimes it is that.

The day before now, maybe one or two years , that days I was just been to BeiJing from Shandong, living with friends in about 20m2 one root, up and down beds, that days I always think if I want spend more time and more attitude to my work, I should I have a stable enviroment, not just with so many friends in just one root. And now , also with these friends, but now we have one big room with two or thress small bedrooms, I have one special root - the book room.  But, now I think I should live alone , and then I will have so many time to spend to focuse on my study and my life.

Maybe it is "此一时，彼一时"
