emotional intelligence

Just get good at paying attention to bodily sensations. It might help to actually try saying things out loud, or writing them down, just going through a list of everything you notice about how your body feels right now. What you will tend to notice over time is that there are certain characteristic familiar patterns of how you are feeling.

A leading indicator of personal growth is how curious you are able to be with all your emotions - especially the ones you weren't allowed to feel as a kid.
