The subs and core values?

I am curious if it’s possible for someone to run say Dragon Reborn to discover what their core values are and hopefully change them if they aren’t beneficial?
I ask because as my wife pointed out to me a few months back her core value is honesty where mine is obviously fairness. Having a core value like that feels almost detrimental to growth and happiness because life isn’t fair and never will be. It’s a major reason I get so frustrated and upset about things that are out of my control and cause me either extreme envy if not borderline hate.

Don’t know about DR, but I can tell you that running LBFH for two cycles woke me up to certain values I held that have not served me well. I’m talking deep-identity-level-breaking-free-of-the-matrix type realizations. It won’t feel great. I highly recommend it.
