How does paragraph 5 contribute to the development of ideas in the text?

Emotional awareness is like a muscle. The more you practice using it, the stronger it will get. One way we can improve our emotional awareness is by getting into the habit of noticing how you feel at different points throughout the day. Designate a couple of times a day to check in with yourself about how you are feeling. Did you just get a grade back from a test? Did you just finish catching up with a friend? Have you been busy working on multiple assignments all day? Are you rushing to get to work? How do these, and your own personal experiences throughout the day, make you feel? You can write some of the feelings you notice into a notebook or your phone or simply think them over. Most importantly, carve out some time to notice how you feel.
