Just Because you put down your pen . . .

 Just because you put down your pen, you come up for air, or you run out of steam, enthusiasm, or inspiration, does not mean you are done writing, and what you have is perfectly acceptable to immediately submit for publication. You just finished the fun part. But that's okay, take a break and walk away from your writing. 

And when you come back to it later with fresh eyes to begin the process of editing you will see and hear many things that need changed. One of the best ways to self-edit is to read your writing to someone else. 

Writing is a process of many steps from original thoughts to planning, outlines, character arcs, that fun first draft, and then the grueling editing which invariably leads to second, third, even fourth drafts.
