What do you recommend as advice for a person who wants to increase/explore their artistic skills?
The first thing I would suggest is to think about what sounds really fun, exciting, or new, and then think about how you can experiment with that. Can you take a class? Look up something on-line or at the library, call an expert and take them to coffee. Push yourself to try something new. The other thing that really helped me a few years back, was using the Artist's Way and really committing to completing the 12 weeks of exercises in the book. This made a huge difference to me when I was trying to figure out how to be an artist after I had left teaching to pursue art. And finally, make sure your definition of art is big enough to include all sorts of inspiring things you may want to explore. Art is about transformation and living more fully.
