The objective of ACT is not elimination of difficult feelings; rather, it is to be present with what life brings us and to "move toward valued behavior".[6] Acceptance and commitment therapy invites people to open up to unpleasant feelings, and learn not to overreact to them, and not avoid situations where they are invoked. Its therapeutic effect is a positive spiral where feeling better leads to a better understanding of the truth.[7] In ACT, 'truth' is measured through the concept of 'workability', or what works to take another step toward what matters (e.g. values, meaning).
