Quick summary: as part of increasing your self-awareness I suggest that you take a look at the topics that really get you ‘heated’ with the goal of coming to an understanding of how you personally identify with that topic. In this self-exploration you might just find that your emotion has very little to do with the topic and is perhaps more related to: an unresolved occurrence from you past, or an attempt to create a stable sense of who you really are (your identity), or both.
