What are some motifs used in Bud, Not Buddy?

One motif in the novel is Bud's rule book.  Bud keeps reminding the reader about his  "Rules and Things for Having a Funner Life and Making a Better Liar Out of Yourself."  By the end of the book, it's clear to the reader that Bud is making up some of the rules as he goes along.  Or at least he is making up the numbers as he goes, because the same rule is listed as two...

One motif in the novel is Bud's rule book.  Bud keeps reminding the reader about his  "Rules and Things for Having a Funner Life and Making a Better Liar Out of Yourself."  By the end of the book, it's clear to the reader that Bud is making up some of the rules as he goes along.  Or at least he is making up the numbers as he goes, because the same rule is listed as two different numbers at one point.  The rules serve as a coping mechanism for Bud.  He always brings up the rules when he knows that something bad is about to happen or be said.  The rules represent Bud's attempts to put some order into his chaotic life.  It's interesting to note that as Bud's life takes on more order and belonging with the band, the frequency of Bud's rule book references slows down.  

Another motif is doors.  Before she died, Bud's mother told him that when one door closes another door opens.  

"And Bud, I want you always to remember, no matter how bad things look to you, no matter how dark the night, when one door closes, don't worry, because another door opens."

Bud realizes years later that his mother was making an analogy.  Bud constantly thinks about doors in the book, and he is always looking for the next open door after a door closed on him from a bad situation.  For example, the Amos door closed harshly on Bud, but it opened the door for him to eventually meet Lefty Lewis and his daughter.
