"The capacity to be alone is the capacity to love. It may look paradoxical to you, but it is not. It is an existential truth: only those people who are capable of being alone are capable of love, of sharing, of going into the deepest core of the other person, without possessing the other, without becoming dependent on the other, without reducing the other to a thing, and without becoming addicted to the other." - Osho
Self love is so important. Because when you're all alone and it's 3 in the morning and you're lying on the floor crying and shaking and wishing it all would end, who's going to be there for you? You. You have to pick yourself up and find the strength to carry on. At the end of the day, you're all you've got.
