How stubborn we are sometimes, the human being always has the need to love someone and be reciprocated, but, once that same person has placed himself in front of a mirror and said "I love myself", I think very few have done that, and that is why we are so accustomed to giving love to other people that sometimes we forget to love ourselves.
Before loving someone else, learn to love ourselves, love our mistakes, our shortcomings, love our virtues, love what we are and how we are, because before you go and love someone else you should first love yourself.
