We are taught through many paths of faith to love others first and ourselves last. The issue with this is, we will continue to search and seek out from others whatever it is we feel that we lack.
Expectations will run high, and when we still don't receive what we feel we had been missing all along, disappointment begins to set in, even leading us to happiness fail. All because we had been taught to always put others first. Never forget that you are so worthy of your own love, and you attract what you are.
