Imagine this... You've been reading this book for awhile now and you're not really interested anymore, but you still keep reading it.  One day you pick up a complete different book and skim through it, it seems interesting. It's interesting. Very interesting. You start reading it and now you can't take your eyes off the book. You even lose sleep cause of it. You just wanna keep reading and reading. The book never gets boring and you definitely don't want to put it down. You're drawn to that book very much. All you do all day at work is think about this new book you have and can't wait to get home and read some more.
You've left the old book behind and don't even want to read it because you've realized that you've been reading something that won't change and it doesn't interests you. You've moved on. Now you're only focused on the new one and that's the only one you want to read nothing else.
You're my new book.
