I have friends that are much better actors than I am that had to quit the business because they couldn't survive the auditions or the rejections, or people just didn't realize how good they were. ↗
Audrey was a princess, so natural, the camera really loved her... James and I kept each other company during all the rejections. We used to meet, have a cup of coffee and went from office to office to get work and never got work. ↗
People could rationally decide that prolonged relationships take up too much time and effort and that they'd much rather do other kinds of things. But most people are afraid of rejection. ↗
