Keeping your heart happy with what you have right now can make a big difference in how you live your life. It doesn’t mean that you don’t work towards future goals, but you shouldn’t spend too much time pining over not having something (like a relationship). Chances are if you are a happy person now, you will be a happy person when you are in a relationship. It’s the idea of being happy with what you have.
