create a booklist and read every book on it

I have a hard time making a list. I don’t know how much books I should put on it…But at least I do know I want to be all kind of books on it =D
The reason why I want to do this goal, is because when I was a child, I used to read a lot! But as I grew older and older, I stopped reading, which, I think, is a sad thing, because I enjoy reading a good book very much and it makes me feel good.
