1) Focus whole-heartedly on my very next task whether it be going to work, cooking dinner, cleaning the litter box, or finding my way way back home.
2) As soon as I catch myself analyzing any part of the audition I stop. I just stop. It's pointless. This is something else that takes time and practice. That being said, in the moments right after the audition is over I do think it's neccessary to note anything of importance. Like significant notes about the production team in case you are called in again or things that you learned worked or didn't work. But after that initial evaluation everything else can drive you mad and bring you down.
3) Make sure that once I have saved any contact information from the production team I delete any emails or voicemails pertaining to that audition. The heart doesn't feel what the eyes don't see. (Or something like that.) I won't throw away any physical sides or scripts yet, but I do tuck them away in one of my acting folders.
4) Look for more auditions of course!
5) Focus whole-heartedly on any acting related thing coming up including auditions, classes, screenings, events, rehearsals, and shoots.
6) Write in my blog or do something creative.
7) Remind myself that getting the audition in the first place is a big deal and means I'm doing something right.
8) It also helps to literally sing the words "let it go" while imitating Frozen's Elsa. Yes, you have to mimick her movement from that scene as well. Trust me, you will feel much better.
