<human>: Can you summarize the given text in a few sentences?

I'll explain. I just graduated this past December. I worked hard, but after a tumultuous last semester I ended up walking out with only a 3.0 GPA. I don't have any tuition debt, but I'm concerned about my career prospects. I was the editor-in-chief of my University's online newspaper, I'm a contributing editor for a up-and-coming arts & entertainment website, and I just secured a unpaid summer internship with my town's public-access television studio. In a year, I want to apply for the Turner Broadcasting T3 program or teach English abroad. After that, I want to take the GRE and apply for the television broadcasting program at Syracuse University.

I'm career-focused and driven, but I can't help but feel like my undergrad GPA is going to be the deathknell of any career program or job I want to pursue in the future.
<bot>: I can't help but feel like I should have done more (better grades, summer internships) during my undergard and that I've inadvertently killed my chances at pursuing a career that I love.
