I think I'm going to write a book.  I'm a little obsessed about it, actually.  It's all I've thought about for the last three weeks.  My challenges:  I'm lazy.  I THINK about it a lot.  I'm less than ready....  I don't have an actual idea for a book.  I just know it's something I'd be good at and so I know I should do it.  The fact that I'm still thinking about it is good, though.  Now...  for the idea part.
