Your values are reflected in the experiences you have in life.
For any experience, what was important about the experience?
For any experience, what did you enjoy about the experience?
For any experience, what did you remember about the experience?
For any experience, what were you proud of?
For any experience, what was fulfilling?
The answers to these questions are your values.
The bigger the experience the more obvious the answers, but in any experience the values will be reflected.
