There is something I feel when I animate something; you can never really understand the character you're animating unless you've had the opportunity to turn it around. Once you've done that, you know it is a three-dimensional object.
I don't have time to sit up and write songs all day. Maybe one day when my kids get older.
For me, my guilty pleasure is that if I don't want to do anything one day, I won't. I'll just sit around, not shower, hardly even eat, and just watch TV.
