It's true when you encounter people who are often times considered "toxic" in your life. These people can be anyone from family members, to your significant other. The love you feel eventually begins to drain your energy and erode your self-esteem. However, it's false when you love people who are worth it, people who enrich your life, people who invest in you just as much as you invest in them. Then your love becomes a valuable asset. I guess what I'm trying to say is it's all about the people you're spending this energy on.
