Everyone has a heart. Its up to you to use it. It puzzles me how many choose to ignore it when it comes to others and then they can't figure out why their life is so full of drama. Be the person you wish to see in others and you may be amazed what a great effect that will have on your life and the lives of others.
It is something I have always felt and have tried to live my life by. Sadly, people often mistake it as being fake because online, it all seems so uncommon. Truth is, I previously put myself in a position of associating with others who I would believe are unhappy with their own lives and try to spread that unhappiness to others. In cases like this, there often isn't much you can do but to separate yourself from them so that their negative energy does not pull you into their world so that you forget who you really are.
