Seize every opportunity.
Had a audition yesterday for the role of a woman between 45-60 which I don't fit but decided to go anyways. I'm 41 but people think I'm younger.
Got a callback and my role was switched to fit my age range. Went today rocked out my audition and even knew the casting director because of a previous booking we did.
More of the story. Don't count yourself out. Network at every opportunity you get because you just never know when your breakthrough is coming or something adjustments will be made for you to fit in.
