Tom has a list of 1201 items on his website called "Happiness".
In his words: "Sometime during the summer of 2001 I decided to keep a list of everything that made me happy to remind me of the multitude of joyous sensations there are to be found upon this earth according to me...I present to you my very own personal reminder of why life doesn't always suck which is my list of everything that makes me happy...".
