Lost in Book Store

Yesterday, I went to a bookstore near my place. I like book. I enjoy reading very much. but I have problem spending money. I do not know how to spend. Always have a hard time choosing what to spend and how to spend. When I was wandering in the bookstore, I can't decide what book to browse. I am lost and wandering. All books seem expensive. In addition, I have no time reading. I have lost my interest, sad~~~.
