I got two Distinctions as well, but the Credits were for a creative writing class and a literature class. Two things I'd like to be good at.
It's one of those times where I think to myself - am I going in the right direction? Should I be doing fiction writing if I'm only getting Credit?
Well... of course I should be! All I can think about is writing, and when I'll next have time to sit and get another chunk of the story out - no matter how crap it seems at the time. So I'll keep going.
And it's good to remember that anything creative is subjective.
