and lost than to never have loved at all.
I would like to revise that:
Better to have loved and learned than never to have loved at all.
Or maybe just better to have loved! How can loving be losing?
If you lose that love in the present, you have not lost it in the past, it is forever yours. If you love yourself, then you never lose love in the present. If you are open, and unexpecting, you will find external love again. Take the moment to breathe and love yourself - focus inwards.
You will never "lose" love - it is within you.
