Even if you’re not an anthropology student and maybe don’t even plan to take a class, the principles of anthropological thinking are still completely relevant. What’s important in anthropology is the approach; our lens is set to panorama, not macro, and these tenants can be applied in everyday life.

Cross culturalism. The world is an interdependent, interconnected mesh of people and cultures that are unique and similar in their complexity and composition.
Cultural relativism. The practice of understanding a culture on its own terms, independent of your own perspective. Using the lens of your own background allows moralization or a judgement of ‘strangeness’ of another culture when it differs from your own background. Practicing cultural relativism opens you to accepting other ways of living. Subsequently…
Acknowledge the external forces (i.e., culture) that make differing opinions between two people that don't have anything to do with right or wrong.
Holism. The world is made of many moving parts that need to be understood together in order to make sense. This means that there are cultural, biological, environmental, and historical foundations for behaviours and beliefs that create similarities, differences, and inequalities between individuals and groups. Nothing and no one is free from external forces that are outside their control.
Reflexivity. Although through practicing cultural relativism, there is an attempt to separate yourself from how you understand others, it is not completely possible. This is where being aware of how your attitudes and beliefs affects your ability to understand other people comes in. This helps to comprehend how our own thinking is affecting how you view others.
Do no harm. By not only your own standards, but by the standards of the people around you.
Use your skills to improve the lives of others where ever possible (by their standards, not yours).
