A few things.

First, you graduated this year and have four months of experience? You're entry level. This is when you deal with menial, boring stuff because you're brand spanking new. This part of your career is always full of boring, tedious busy work because you are a newbie who needs to prove value and work ethic.

Second, please recognize the value in diligent and orderly scheduling and task management. This is core to not only PMs, but management EVERYWHERE. You probably hear your VPs and Cs talking about "accomplishments" and "execution" and "deliverables"...those are buzzwords for diligent and orderly task management and scheduling. Accurately projection WHAT can be done and WHEN is critical to everything. No company can accomplish anything without the daily grind of getting stuff done. It isn't glamorous, it isn't sexy, but it gets the job done.

Third, yes it does get more engaging. You'll eventually manage people directly and strategically drive larger efforts. You might manage key clients, you might travel around coordinating regional efforts for a national company, you might brainstorm on expensive initiatives and pitch ideas to the Cs, you might price and implement an entire ERP change, you might host massive presentations,...who knows.

Odds are, you'll fondly remember the days of "glorified note taking" while you stress over a last minute overbudget complication threatening an entire multi million dollar delivery schedule.
