When you love yourself: you love your life. And that is the closest we know to be a happy person.
And you want to be happy, right? It feels like your birthright. Even though I can't specifically point at anyone who is happy... it IS your birthright.
Birthright or not birthright, we all want to be happy... even though no one has been able to explain how to become happy... so it seems that it will remain a desire... never to be fulfilled. Hope and hopeless... or resigned is our dominant state.
The closest experience to happiness is contentment, with life, with yourself.
When you love yourself you love your life... but how can you?
