Slacking?

I guess I would say that I've been slacking lately. I know, it's hard to believe, but it possible that I haven't been living up to my potential.

One of my bosses gave me a list of names and personal phone numbers of people that work here and she wants me to make sure it's up to date. She gave it to me last week and when she checked yesterday to see how I am doing on it, I had to tell her I hadn't started yet. I wonder if it is just because I am lazy unmotivated or because I don't like the idea of a whole list of personal phone numbers being available to almost anyone.
