I think I always had a strong creative streak before Straight, which showed up mostly in my obsession with music and clothes (as a form of self expression), and having my own ideas about everything. Straight repressed all creativity....it was practically forbidden!
But oddly...my creative side really grew in a lot of ways while in Straight. I remember riding in the car to the building how I got lost in admiring the simple beauty that is abundant in the world that I never noticed quite as profoundly as I had before Straight...nature became an art form to me so to speak...Plants, trees, the sky, etc all look beautifully different....
After Straight, my creative outlet became photography...of course my obsession with music and clothes and thinking for myself came back fairly quickly.
And now "professionally"...my creative/thinking outside the box side shows when asked to solve problems or come up with new ideas, etc. It has also showed in law school too....in of all places...legal research and writing assignements.
Funny thing...I remember in college classes and other "professional" internships/jobs how sometimes people try to actually teach the idea of thinking outside the box...I laugh to myself because although I obviously think those people have the right idea...thinking outside the box or "coloring outside the lines" cant be taught...either you have it or you dont.
And yes...I think sprituality can be connected to creativity (I have experienced this) though I wouldnt say it always is.
Here's a general theory I have---I bet a lot of kids put in Straight were creative...creative people often are misunderstood and labled as "troublemakers."
