The time thing's a great point, Stephanie. Certainly not one I considered when I was 15 and trying to find a publisher. =) And not that I stayed up late and slept till noon as a teen, but there were always other pulls on my time.
I was kinda amazed when I got to college, had a killer workload, and looked back over the past year or two. Once I really had to prioritize my time, it made me wonder what in the world I'd done with it back when I had some, LOL.
