Becoming a happier person may mean doing some work to identify what you really want, and then making some life changes to head toward getting there. It might involve working with a therapist, coach, and/or a trainer. Maybe making peace with some things. Maybe even trying medication. It’s a process. There’s no easy quick fix. And finding a new partner won’t do it either. Better to start the work now while single, to become someone who can be a good partner in a healthy relationship.
