Bored in the workplace

As of August 22nd, I will have worked in this corporate job for two months. It seems like the longer I'm here the less I actually want to be here. In a rush to find a job out of college, I didn't take the time to find a job I would actually enjoy having. But of course while looking for one, any job that paid well seemed like a good job. I spend most of my eight hour days counting down till I go home, or playing games on my phone. I finished two mangas in maybe 3 weeks. That's the kind of time I have on my hands. I always figured a new job would be exciting, or maybe just more than this. I heard stories from my coworkers of late nights to finish proposals etc and I'm trying to figure out why it takes them so long. I feel like I can finish everything they give me in about 10 minutes max! I have yet to have a full days work of work even when I was working on a proposal. I'm told things will pick up, but in the meantime boredom is getting the best of me.
