Well I finally passed the CCNA with a 933. Success!

As I continue to look for a job, hopefully within the networking field, I'd also like to continue to study to not only keep up to date with what I currently know, but also further my skills.
I assume going straight from CCNA to CCNP without on the job experience would be much too difficult.
Does anyone have some suggestions as to something I could move on to with self-study and not have TOO much trouble grasping the material? Looking to head in the direction of another cert.
