How do you notice your values are violated when things slip slowly? One way is checking in with your body.
If you are pulled towards creating some big massive impact out there, the kind that touches lots of people, you need more pairs of hands. Shared values are great to build alignment.
Your values are one of the things that make you YOU. They help you figure out what right and wrong look and feel like. They are also among the drivers of happiness (when fulfilled and respected). It helps to become a bit more conscious about them.
