Behind the 8 ball

Or at least I feel like I am!  I feel like I'm being pulled in 3 different directions at once, and I don't know where to start!  I've been proactive already this morning- I got off work an hour early, so I came home and wrote  1 of my 4  messages, but still need to call people.  But as it's only 8:10am, it's a bit early to be contacting businesses! I am in charge of the book fair at the elementary school we attend, and I need to change the spring book fair.  I called the woman 4 days ago, and she still hasn't called me back.  So this time I'm just calling her cell, instead of her business line.
