Beliefs are what we think to be true. Values are what we think are important.
When we mix the two, and take our beliefs to also be our values. Then, it’s hard to question our beliefs since they are now part of who we are, our identity.
Question your beliefs, and be ready to change them as new information comes in, and you reach new understanding. Be curious, find ways that support your beliefs or ways against them, argue them to better understand not only your beliefs but also the beliefs of the other side.
Question what you believe to be true, often!
