If I am to become a great writer, I must be consistent. For so long, I've viewed writing as a hobby, but I want it to be what i DO. It's so easy to get caught up in the pressure to write something "good" all the time, when I should be focused on writing. As long as I view it as a hobby, that's all it will be. Something to do in my free time in hopes that it's "good". I'll never truly be a writer with that view.
If I am to become a great writer, I must become unafraid. In my writing, I leave my raw side untapped. I will share a certain degree of myself, but I hold back. Anything that delves too deeply into the painful, sad, erotic or even joyous - I keep that to myself. If I can become uninhibited in my written expression of hurt, desire, et al. I think that will definitely serve to my credit.
If I am to become a great writer, I must see things to completion. There is a plethora of unfinished work attached to my name, and that really needs to change. Becoming a serious writer will require me to take my writing seriously. It's just going to take me buckling down to get the job done.
