Where Is My Heart?

Usually, I can tell where my heart is based off the things that I am chasing after. If I am locking myself up in my room all day and isolating myself from the people around me in order to work on homework, my heart is chasing after getting good grades. If I find myself constantly hanging out with friends rather spending a little bit of time reflecting on things, my heart is chasing after friendship. But what happens when we allow ourselves to isolate ourselves from everyone and hide away? As I was thinking about this, the answer isn't that my heart is chasing after nothing. Obviously, there is something that my heart is either avoiding or wanting to spend time alone in. When I isolate myself, however, is it doing me any good? Or am I allowing myself to dwell more and more on the things that are keeping me down? And, when I allow myself to do that, am I allowing myself to harden my heart? The state of my heart is not something that should be taken lightly. Honestly, it is something that I should be greatly concerned about and attuned to daily. How do I do this, though? First off, I need to spend time in prayer on a daily basis, asking God to protect my heart. Not just from others, but also from myself. Also, I need to allow him to keep my heart soft. Only He can do this. Instead of allowing my heart to harden and become desensitized, I am going to turn to the one who can help in anything.
