I think it has a lot to do with what they said about your goals changing. When I first started painting a decade ago, my goal was to do a good oil portrait. But now, painting has become so personal and spiritual to me, that my goals aren't as external like they used to be. I realized a few years ago that while I am in the process of painting something, I have no fear in my heart. Exploring that has become more of my goal, and one could spend many lifetimes working through it.
