why should I think in English?

I am LJY. My English is poor. But I want to improve my English. Someone tells me that I should try to think in English and use English as a tool. I think she is right. My first step is thinking the objects around me in English. So, let's do it.

I see an electric fan. I see my computer in right front of me. I sit in my bed with my laptop on my lap. There is a box of books on my right side. A red bottle is in front of me. I saw some beautiful girls in the library today. My bed is soft but it is ok to me.

I am tired and I go to bed now.
