I’m great at auditioning if the character I’m playing is supposed to be a nervous guy.
It has been suggested that people become actors for the same reason they like extreme sports. Both have similar challenges that produce an adrenaline rush and test one's vulnerability.
The feeling of falling from an airplane for me as a skydiver is almost the same as walking onto a stage in front of a big audience or having a film director's camera in my face. The desire to survive is pretty much the same too.
The ACTING challenge (for me anyway) is getting out of my own way ... giving up control of my body to the CHARACTER so he can jump inside and become alive. It feels uncomfortable at times when he does things I wouldn't do ... or uses secret fears & emotions in my own personality to express himself.
It's fun, though, when he CUSSES a lot. I don't know why, but for some strange reason it feels good to say "#>%!" and "≠?¤#$" in front of a lot of people and not get in trouble for it.
