Congratulations! You're Done! Now, you can bask in the glory of a job well done. You have made a sale or got your stuff to a show. Who cares what it was? It's over!
There is only one catch: You might have to take everything you just got to wherever you got it, right back where it came from. Bummer right? Well, I can offer you one piece of advice: Tell whoever has your stuff not to throw out the packaging when whatever you are doing is over... Or at least until the money has changed hands. You've already spent enough on this, and having to buy all that material all over again is not fun.
But why dwell on that? Enjoy your life! Have a beer, pat a dog, or do whatever it is that you like to do. It is over!
