Sometimes your heart is saying "go on, eat that whole pan of brownies!! Maybe those times aren't so great (although tasty), but most of the time our heart will tell us what we need to do to be where we want to be. For instance, today I chose exercise over a pan of brownies, because my heart decided that it wanted to be healthier more than it wanted chocolate....it was pretty close though.....the brownies almost won.
Feel free to share this with anyone you love. Especially if those people love Darth Vader, because he followed his heart, right into the arms of the dark side, but still, in the end his heart gave him back Luke, so there was that.
