Question

Georgia O'Keefe has been quoted as saying something like the following, although there are many versions of the quote:
"I've been absolutely terrified every moment of my life -- and I've never let it keep me from doing a single thing I wanted to do."
What is the precise phraseology of this quote, when was it spoken, and what was the context in which it was spoken?

Answer 1

Why don't you contact the Georgia O'Keefe Museum in Santa Fe, New Mexico? They have an extensive collection of publications and other materials.

I exhausted my avenues of research on the web as well as the publications I have in my studio about her. I could not find any source for the quote.
