Sometimes you learn a lesson and then you just have to learn it again. The act of loving is natural or at least it's supposed to be. The emotional baggage that we all carry with us determines how much love we can accept. Loving without expecting anything in return is our highest calling. It's what the universe is designed for. Maybe you never get good at it so that you can just keep practicing.
It's all beautiful out there. I wish all the love in the world for all of the lonely people.
