Crush School Testimonials
“The author’s style reminds me of Malcolm Gladwell in that he combines a little science, a little wit and lot of his own brilliant mind to create a book that turns the seemingly obvious, but surprisingly difficult into the totally understandable. ”
“Speaks right to teens. Thank you for saying everything I’ve been trying to tell my son in a language he understands! Easy to read and understand. Short and to the point. Great for the short attention span of teens.”

In this classroom Mistakes are Expected, Respected, Inspected, Corrected!
Learned helplessness is a result of years of conditioning that mistakes are bad for learning. Nothing is further from the truth - some of the most powerful life lessons come from making mistakes, reflecting on them, and growing as a result.
This is a PNG Poster you can print and display in your classroom to encourage a culture of risk-taking and learning from mistakes.
