You rarely revisit a project or assignment after you've turned it in. When you're done, you're done and are ready to move on to the next thing. Indeed you're so confident about your recent performance that you've already signed on for something else. Unfortunately Mars will be forming a square to Saturn on December 8th. Mars/Saturn squares  are the “not so fast” aspects in Astrology that force you to stop and review your work. Chances are you forgot to dot an i or cross a t. It's annoying as all get-out, but the sooner you take care of this, the sooner you'll be on your way.
