It's been a month....that was fast.

I get so excited with new things, but I'm afraid I get bored to quickly. This has been most prominent with jobs, jobs that I really enjoy, but I feel like its the same thing over and over and it isn't fun. Should it be? Is that what work is for? Can it be? I try to find ways to make it new and exciting to me. New variations, new attitudes, new people.
Thoughts?
