Type, Age and Hair
You can be the best auditioning actor they'll see all day, but if you're clearly not the type, if you don't fit the suit, you're not going to get cast.
Having to adjust your self-image, re-evaluate, self-assess (or better, have someone else assess) is part of the ongoing and at times painful quest for employment.
Talk about readjusting, my headshot is over 4 years old. I'm told that I look "the same," but come on there is clearly a change. I need to update my headshots. I need color shots. What am I waiting for? Note to self: Do it!
I know I'm not realistically going to get cast on a soap opera. That is not happening. My hair is thinning and soap opera guys always have freakish wild manes of hair with perfect hairlines.
Learn your type now, not your type from 10 years ago.
Accept your type.
