Yabba dabba doodle
Improvised sketching is one of the most important habits a person should adopt. It’s a fancy word for “doodling”, and defaces just about every important document or notepad I have come into contact with since I was 5.

When you’re young it is considered a bad habit, like finger nail biting or cursing. I have yet to find a downside in visually depicting random thought. Some of my best designs were concieved in a marathon of mindless doodling during a rather boring work meeting.
