A LITTLE JOHN GREEN THINKING
A good place to begin.
01
Nerds are allowed to love stuff.
Follow the subject you light up about. Caring deeply is a good reason to start learning.

02
The truth resists simplicity.
Look for context. Make room for nuance. Let what you learn change how you see a person, an idea, or the world.

03
The test will last your entire life.
Learn for the decisions, conversations, and everyday moments ahead. Understanding travels well beyond the classroom.
