I blog on Brain-Based Learning, Metacognition, EdTech, and Social-Emotional Learning. I am the author of the Crush School Series of Books, which help students understand how their brains process information and learn. I also wrote The Power of Three: How to Simplify Your Life to Amplify Your Personal and Professional Success, but be warned that it's meant for adults who want to thrive and are comfortable with four letter words.

“Keep It Simple Stupid! That’s what my favorite teacher in High School, Mr. Dennis used to say. Besides being an awesome teacher, dude had a point:
WE TEND TO OVERCOMPLICATE THINGS.
Don’t feel bad if you do it, because it’s human nature.
Multitasking is one way we make a mess of things.”
