Find a teacher. Then be a good student. Listen to the instructions, and do your homework.

I took a workshop recently from Doug Walton. It is good for me to get out of my head and habits and follow someone else’s instructions. Every year I try to take at least two workshops, and during the workshop I try to leave behind what I know works and try whatever method is being taught. It is awkward, like writing with your non dominant hand. The results usually aren’t that great, but during the process you grow and when I get back to my studio I have some new trick or technique in my tool belt.
