Be ready is different from get ready. The Christian walk is one of constant preparation, but at some point there is a "be" ready. Applying this to my writing, I could spend a lifetime reading about the craft, practicing, preparing, but if I never get to doing I'm not going to progress. Sometime I have to stop collecting information; sometime, I have to take the plunge and write. Not only write, but send it off to the editor, take the risk. Take the risk and knock on agent's doors.
Frankly, this stinks but it's necessary to grow and improve as an artist. The truth is that I can have all the natural talent in the world, but if I never prepare, grow, improve, it will amount to nothing. So, as a student studies for years to earn a degree, I too, put in necessary work and sweat so that I will be published. I don't want a publisher to finally knock on my door and wait while I scramble to get my manuscripts up to snuff.
Be ready, not get ready.
