For me, the best way for me to maintain the concept of evolution and creativity is to constantly find something that’s a challenge.  When I’m being offered something, or I’ve got to put food on the table — I’ve got a family, I’ve got to put food on the table — but this is what I do as a living, and it’s my calling. Whatever So for me it’s like, “What is going to challenge me?”   I’ll have a couple of options, and whatever is the scariest is almost always what I end up choosing, because I figure that’s where there’s something to be learned. And where there’s something to be learned there’s evolution.  So I’m always looking for a challenge.
