I graduated with my Bachelor's in English in 2004. Technically, the whole degree was English with an emphasis in creative writing and a minor in professional writing. For three years now I have been kicking around the idea of returning to school but I don't know what for. I have considered both an MFA in fiction and a second undergrad in ....well....something. Maybe graphics design, maybe web programming.
I'm looking for some first hand experiences, and a little advice. Who has done it - taken a few years off and gone back, either for a masters or doctorate or for a second (or third or forth) bachelor's? If you went for a second Bachelor's was it something totally new or something to complement or enhance what you already had?
Also, what would I need to do to improve myself in the eyes of a grad school admissions committee/board? My major GPA at time of graduation was a 2.6 and my overall was 2.3 (I have a few regrets about some of the skating I did through college

). Generally speaking, can (should) I go back and retake some of those C classes to try to get a better grade before even applying?
