Some superfluous advice for the Beginning Writer:
Make sure you read as much as you can. Branch out of fiction, find a vein of philosophy you enjoy—that will help to build your thinking muscles for later on, when you’re ready or want to dip into deeper concepts.
(A semi-related anecdote: when I was a teenager I wanted to be a poet. I understood that poetry needs to be wed to music to garner the praise I was after, at least in the culture I’m from. And seeing as how I was shy and more often than not disappointed by the lyrics of the bands I liked, I decided to focus on writing stories instead. Years later, burnt out on stories, I picked up a guitar, and found that songs fell out of me, like rabbit poop scattering across the carpet. It puzzled me how much a struggle it was for the musicians I knew to finish a song—when, as a writer, all I needed was a good chord progression, a change or two, and the lyrics came on their own. I knew how to listen for them. Which goes to say: other pursuits will feed into your writing, and give you an advantage, or, rather, increase the value of your product. (As an aside, I can’t record music for sh*t, but I love writing songs, they alleviate my poetry compulsion))
Also, write for people and write for yourself. Get good at action sequences and descriptions, but experiment with language when you can. I believe that Writer’s Block is not so much an absolute block as an indication that your imagination wants to take things in a different direction. As the proverb goes: “There is always fruit in the forest.” So: be playful. Remember that the entirety of writing is a human construct, and there are no absolutes, only varying degrees of clarity, immediacy, and sympathy between writer and reader.
