You are too intro-spective.
You are too in-secure.
For a performer (STORY-TELLER) the only feedback you require ... is from your audience.

MORPH
CONFUSE!
Do it over and over and over again Thirty times a week for 50 weeks a year for ten-years
You will develope the non-chalant hide of a rinosaurous, the witty-ironic teeth of an aligotor, and the guile of an unsavory politician.
Keep at it...you might get there.
Sincerely,
Gargoyle
