Here is one of a huge collection of sketchnotes by April Wu
I've always been a doodler since grade school. The sketchnote army inspired me to pick up this habit again, especially in a brand strategy course i'm taking now in graduate school. My professor's lecture includes both course materials and real-world experiences that he shares with the class. He especially loves to use quotes that are aligned with the concepts he is explaining, or simply to inspire us. My doodling may sometimes be off topic and simply an observation of the environment that the class is in, but they are good re-call cues to my ideas when I revisit my notes!
