Artists and creative folks. To be a creator, you need to expand your mind, experiences, boundaries, get out of your comfort zone. I cannot emphasize enough the life-lasting power of travel, and I don't mean flying somewhere and sitting in a resort. If I could go back in time, one of the things I would tell myself would be to travel more, somehow, someway, suck it up - travel. And go live somewhere for a few months. One of my biggest regrets is not taking one of those "Teach English" gigs in Japan for 3-6 months. As always, the much-missed Anthony Bourdain sums it up wonderfully here, so please read it and think about how it applies to your artistic outlook.
