Living by impulse can be thought of, both positively and negatively. When glorified as a positive, impulsivity is spontaneity, living in the moment and making the most of the here and now. As an ideology, it focuses on the here and now of life. Philosophically speaking, the past is over and cannot be retrieved, the future is yet to happen, so now is really all we have in which to live our lives. It also connects with passion, emotion and living life in response to emotions felt in the here and now, as a kind of authentic living. It also makes for a more unpredictable, hence exciting life.
