We have a lot of defined deliverables in our lives– work that comes with a deadline. And you bust your ass to create a good product, produce good work, and line yourself up for rewards. Which is great. But remember that once your deliverable is presented/turned in/sent into the ether, there’s not much more you can do. Don’t fret about the results. Let it go.
Worrying about the deliverable’s reception doesn’t do anyone any good. It makes you stressed and it annoys your co-workers that have to listen to you.
This is not to say that you shouldn’t do all you can to position your deliverable in a good place. You should. But all the accessory stress that comes with worrying about the fate of the deliverable should be avoided at all cost. After all, who has time to worry? Go work on your next project.
