The opposite of compulsiveness and impulsiveness is freedom
When we act compulsively, this means that our emotions, not our awareness are controlling our actions. We are neither our emotions nor our thoughts; that are just a result of our brain processing experiences from our five senses.
If we were our emotions or thoughts, then our total being would just be based on what we have experienced. On the contrary, we are the consciousness that can see these emotions and thoughts for what they are and understand that they are like passing clouds in the sky.
When we are no longer slaves to our impulsive reactions, then and only then are we truly free.
