Uncertainty- (is this the topic or am I merely uncertain about what to title it?)

As everyone around me went mad this year trying decide what to do with their lives I've thought a lot about the future. For a while I was a little stressed out about the terrible question "what do you want to do with your life?". Right now I'm content with not knowing, but I still think about it. After being at college for a year I am less sure than when I arrived. I know I want to write, but that is general. Yesterday I stumbled across these lines by Adrian Plass as I was reading one of my books, it is about writing (surprise, surprise) "In the process I began to learn ( and am still learning) that unless my writing and speaking is rooted in real relationship with God and Man, there simply isn't anything to communicate". This is obviously true, but in a larger sense (quoting from one of her favorite speeches again) I don't want to waste my life writing something meaningless while I could have done more. I know every job has a purpose and you don't have to part of some grandiose organization to make a difference, but I want to do the most I can with this little bit of life I have. So I go back and forth in my mind, fiction, nonfiction, fiction, nonfiction. I read something by one of my favorite authors about why they write fiction more than nonfiction, unfortunately when I was looking for again and I couldn't find it. But I didn't come across something else I liked " It's simple really. It makes me choke now. My search for truth and meaning has been so exhaustive that giving up the discovery (writing) or the sharing of what I've discovered (writing) would be subhuman for me. I write because I must write. I have paid a huge price to write. I've been richly blessed because I write."- Ted Dekker. I've always known what I want to do, I must write, I will write, I have to write, but the question is what?
