Why Do I Wait?

I am giving a lapbooking how-to class at our local homeschool convention. When I agreed to do it, it was months away. I just checked my calendar. It's embarrassingly close. I just started to put together the supplies. And, now, I'm at a standstill until I get more supplies. Like paper and card stock. I have to decide whether to go now (and take all four kids) or wait until later (when I won't feel like going anywhere). Silly me. Waiting until 8 days before said class to actually put it together.
