You do not get a second chance. Just know that there WILL be a next time and you will get other auditions. If you have been rejected many times in your life, then one more rejection isn't going to make much difference. If you're rejected, don't automatically assume it's your fault. Perhaps the person is busy or not feeling well, or genuinely not interested in spending time with you.
Rejections are a part of everyday life.
Don't let them bother you. Keep reaching out to others. Keep reaching out to others. When you begin to receive positive responses, then you are on the right track. It's a matter of numbers.
