For me it's about focusing on the objective purpose of the work. What do I want to say and am I saying it effectively. Is the negative feedback because my idea is not clear, or do I need to work on my skill level so I can make the thing I want to make? Embracing the process from the perspective of growth makes it easier to let go of ego.
A saying I love: "The singer is for the song, not the song for the singer."
