About this quote

Thinking for yourself takes work and a bit of bravery. Where do your beliefs come from? Check the sources, weigh the facts, and be willing to change your mind when the evidence points a different way. Start small: question one trusted claim a week and explain your reasons out loud. That practice builds confidence and makes your choices your own.

When to use it

• In a team meeting when the manager repeats a plan I doubt, I remind myself, 'Have courage to use your own understanding,' and I ask for the numbers behind the proposal.
• Before I include a famous study in my thesis, I say, 'Have courage to use your own understanding,' then I re-read the methods and run a quick check on the data.
• When a trainer suggests a new diet, I tell myself, 'Have courage to use your own understanding,' look up the research, and talk it over with my doctor.
• If a friend pushes a get-rich-quick tip, I think, 'Have courage to use your own understanding,' write down the risks and fees, and sleep on the decision.
