Whatever makes you happy is a common phrase that indicates that someone wants you to follow your heart and do what brings you the most joy. While this phrase may be commonly used, there are a handful of synonyms that can be substituted to express the same sentiment. Things like "follow your bliss," "pursue your passion," "live your best life," and "do what feels right" can all substitute for "whatever makes you happy." Its importance lies in the fact that it recognizes that everyone's definition of happiness is different, and that the key to living a fulfilling life is pursuing what resonates with you personally.
