You know the cliches, right? No one can love you if you don't love yourself, and who will enjoy your company if you don't enjoy your own?
It is not that we must rely solely on ourselves, but the fact of the matter is, when it comes down to it, we must only answer to ourselves. When you feel good, the world feels good along with you. And feeling good comes down only to the source of your being: you, and you alone.
Great question Ashantina!
