<p>My first semester of college, I wrote my papers on a typewriter. Did all my research, let it percolate around in my head for a while, sat down and started typing, turned in what came out. No outlines, no revisions, no nothing. My papers got good grades. 
Even with computerized word processing, I’m more of a revise-as-I-go writer.</p>
<p>There’s nothing wrong with writing succinctly; that’s a valid stylistic choice. Or with not writing multiple drafts; what matters is the quality of the output, not the number of iterations it takes to get there.</p>
