Do not avoid conversations about your artwork. When you are asked to explain your work to others it helps you to clarify and distill your ideas. you benefit from these interactions, especially when the people asking are truly interested in the work. When you are asked to defend your ideas, you define them, hone them, and invest in them. You may state your thoughts and opinions, but you wont truly know where you stand until you are asked to defend your position. This is why presidential debates, and debates in general are important. It’s great exercise to defend oneself. It makes you stronger. In art you will be asked to explain your choices, be it material, subject matter, or style. Embrace the opportunity to have conversations where you are asked to defend your position, or to justify your choices. See this not as criticism or evidence that your choices are wrong or invalid, but as an opportunity to be pushed further into your certainty.
