Before I found architecture and interaction design, I was (and still am) an avid drawer. It started out as doodles and squiggles, but eventually evolved into more refined drawings, with the help of my teacher, a Chinese artist named Karl Bang who specializes in watercolor, landscape drawing, architectural drawing, and portraiture.

I didn't know it back then, but I learned two important practices from him that I now abide by as an interaction designer: 1) being intentional in your output 2) refining that output through slow and steady iteration. In drawing, every stroke must count towards something, whether that’s depth, shadow or definition. Moreover, every illustration should start out first with broad outline strokes, then slowly filled in with more precise and detailed ones.
