Why I shouldn't read a trilogy

Enjoyed Catching Fire book 2 in the trilogy. But now I'm waiting on book 3 which is now out.  My lovely neighbor girl, Kara, has it and is reading it. But I want it now! I haven't read anything in about a week, I couldn't seem to get into anything because my brain is still in these books. Which means my project is on a small hold. So note to myself try not to start a trilogy and definitely not a series while doing this project.
