If you can’t explain your process to a ten-year-old… it is too complex.
When you are preparing for your next meeting consider whether or not the ten-year-old version of yourself would understand your message. If not you need to refine it.
To truly know something you must be able to teach it. To truly master something you must be able to teach it to a child.
My counterpoint is that if we build systems so complex that children simply couldn’t understand them… in reality we don’t understand them either.
Could you convince ten-year-old you that your idea makes sense? Would the younger you part with their lunch money to invest in your plan? If not you may need to simplify things.
Simple is beautiful. Simple is elegant. Simple is rare.
