I have a feeling that a lot of my fellow graphic design students are introverts. It's interesting how easy it is to slip into a creative zone in my classes. Normally that's something that the average extrovert will become alarmed when they encounter, feeling the need to fill the silence, make a comment, ask you if I'm alright, etc. All of which makes focusing on a creative problem very difficult!
I don't know if it's just that we're all creatives here or if we actually are all introverts, but it's nice to not feel like I have to apologize for zoning. Everyone understands because they're doing it too!
If you've never experienced a "zone", doing something creative can put you into a mental state of concentration that blocks out outside noises and distractions. This is a huge reason I dislike photographing family events that I attend; once I go into the creative zone, I'm pretty much not mentally present at the event anymore! Lol. When you're trying to be creative though, that's just what you want.
Anyway, all this to say that I love the feeling in my classes. The permission to zone, to create, to think, to feel... it's very refreshing and invigorating to me. :)
