Its not selfishness,
Its self recognition,
Self respect and self worth.
Loving yourself is the first step to loving someone else genuinely,
How can you love someone if you don't love yourself?you're the only person whose thoughts you know and if you can't love that person,how do you love the next person?besides you can't give what you don't have. Love yourself.Not to be selfish but to realise yourself and what you can offer.
