Passed CCNP V and I don't know ....

.... Fill in the appropriate word you think goes there. I have been studying for this cert for quite some time and I'm on the tail end and I don't know as much as I felt I would know at the other side of the tunnel. Before I embark on IE I plan on getting stronger in a lot of areas of VOIP and networking in general. The certs are cool to have and I can pass pretty much any technical interview thrown infront of me, but I would really like to be a expert. 10,000 is the magic number of hours needed to be considered one, so I'm a long ways off.
