I have this habit. If I have the sides two weeks I learn them and prepare. But when I go to an audition and hear nothing. I still work after the audition until I feel I get nothing more from it. This can take more days and weeks. Why? I feel I can learn more from it and grow. I am not expecting to get it.

But one time it did save me because I did get a part which an actor was fired for not preparing.

So how many people do this?

I've learned to quit overanalyzing stuff so I want to forget about it and move on. Normally new sides get printed on the backside or they get thrown away.
