As an artist, one will get several no's for each yes. Rejection is all part of the process. In acting, you are chosen from a headshot, called in to read for a part that the casting director thinks you may fit. If they like you, you get a second (sometimes a third or more reads). Then a producer and director will watch you, and their opinions will be the final decision. A lot of people will sit and discuss your merits, and your shortcomings. And, if they say no, you will never know how close you came to getting the part. You do not get a call, feedback, or anything of the such. Instead, if you hear nothing by the time the process was due to end-- well, you didn't get it.
