The book I have talked about the most is "I Know This Much is True" by Wally Lamb. He has influenced me in my own writing. Also, I know this sounds a bit cliche, but I live by the "The Secret"
Memoirs (Rage Against the Meshugenah, Running with Scissors, An Education, Magical Thinking, Possible Side Effects, Me Talk Pretty One Day, etc.) were what got me into blogging.
Also, Harry Potter.
That inspired me quite a bit, as far as reading/writing goes.
As well as Catcher & the Rye.
