Am I "good enough" to be a writer?

This is a question I've pondered since I started taking writing seriously, since before I started taking writing seriously. It's what held me back from starting sooner. I never thought my work was really good enough to consider myself a writer...I didn't know if I should even try it. 

I asked my mentor, a published author, about how to navigate this question. I asked him how he knew when he was good enough. How he knew his work was good. He laughed and told me that out of all the people out there who want to write, if I'm even asking the question if I'm good enough, that shows I'm already on the right track. That I already know the answer to the question.

Writing, like all the other arts, is subjective. What some love others hate. What makes sense to me might not make sense to others. It's made me wonder what "good" means. How to define it. I haven't figured out the answer yet. 

I'm hoping to revisit this question after I've published some work, even if it's just online. After I've gotten deeper into the craft, after I've explored more of who I am as a writer. I won't know how people receive my work until they read it. I won't know how I feel about my efforts until I finish them. As I wrap up the honors experience side of things, I realize that even having somebody read one of my pieces is a huge step forward and something that I'm proud of. The fact that my off the cuff writing was judged with positivity and the fact that I'm making more progress now than ever is so encouraging. Hopefully with more time and more words on the page I'll get closer to a definition of "good". But for now, I'll have to rely on my intuition and have faith that maybe I do have something, that "spark" after all.
