I hope I didn't sound bitter in the bad sense, but only in the sense that wine is more pungent than juice.
Funny, I have never thought of the bad experiences as "nurture", but rather as "environment." To me, "nurture" is more about the love and acceptance, encouragement and support of family, teachers, coaches, and community.
My main point is that many of us do not fit the European-American male template of education, self-image, career path or the timing of various rites of passage, yet have different abilities to learn and grow, and shouldn't be counted out or dismissed without proof. I often think of the Aesop's fable of the tortoise and the hare.
I'd say treasure the adversity as the fastest, most efficient and most thorough way to squeeze out the old genetic juice.
Thought not the least painful.
