How can I get motivated and focused again at my dull office job?

I started a new job 2 months ago and was seduced by the personal freedom (having my very own mustard yellow cubical and the ability to decorate it as I saw fit!), access to knowledge and power (limited Internet browsing) and financial wealth (12/hr). But lately, even with all these wonderful attributes, entering data for a phonebook publication just doesn’t have the same glamour and mystique now that I’ve ventured behind the proverbial curtain. How can I once again recapture the magic of seeing my computer for the first time and thinking, no knowing, that I had finally come home? It’s all just some commonplace now. How did my dream become so mundane and what can I do to curb the disillusionment and despair?
