Sketch, Sketch, Sketch
This is really nice perspective on the purpose of UI sketching. Sketches aren’t a qualification for artistry but a tool to explore a lot of ideas quickly - allowing the continuum of the design process to move forward. I would note - save all sketches. Review them and make your own notes about what you think works, doesn’t and what could use some discussion. Preserve your ideas so that you can share them with others you feel should be a part of the design process. What you thought was a trash-worthy idea might turn out to be a treasure to someone else - sparking a conversation that ends up somewhere completely unexpected and wonderful.
