What does Jordan Peterson say are the 12 rules for life?

Rule 1: Stand up straight with your shoulders back. Improved body language with a more assertive posture will make people look at and treat you differently. You will also improve your self-esteem.

Rule 2: Treat yourself like you would someone you are responsible for helping.You need to care for the person you might be in 5 or 10 years, not just the person you are today. Care for yourself as well or better than your pet, mentee or significant other.

Rule 3: Make friends with people who want the best for you. Would you recommend your current friends to your mom, dad, sister or brother? If they’re not recommendable are they actually good for you? True friends genuinely care about what happens in your life. 

Rule 4: Compare yourself with who you were yesterday, not with who someone else is today. Upward comparisons only bring about feelings of inferiority. Instead focus on your growth over time rather than wishing for what others have.

Rule 5: Don't allow your children to make you dislike them. Fear of their anger is no reason to avoid discipline. Rule 6: Anyone unable to manage their own household has no business blaming the world or managing anyone.

Rule 7: Pursue what is meaningful (not what is expedient). Pursuing happiness is futile. Rather, pursue a life of meaning by helping others or striving for a goal that brings deep, lasting satisfaction. Happiness should be a byproduct not the target.

Rule 8: Tell the truth – or, at least, don’t lie. Aim for absolute honesty because lies grow and have a negative cumulative effect. Rule 9: Assume that you're listening to something you don’t know. Assume that their thoughtful and genuine conclusions are worth considering.

Rule 10: Be precise in your speech. Healthy conversations are a core component of a healthy life. Be open and honest with those around you to prevent the chaos and confusion that comes from uncertainty.

Rule 11: Do not bother children when they are skate-boarding. Parents must recognize that children will engage in risky behaviors. Rather than helicopter about, allow them to problem solve on their own so they learn to self-regulate.

Rule 12: Pet a cat when you encounter one on the street. The world is full of suffering, so seek and see the beauty in your ordinary everyday life.
