I like this quote, firstly because it deals about love. Love is a subject that is wonderful and amazing, but also mystifying and tragic. I also love this quote because it comes from someone who writes SciFi. I'll admit that I love SciFi; yeah I'm a little bit of a geek about it. Hey, ya gotta love yourself right?
Anyway, there are many forms of love. I would suggest trying to expose yourself to them. As Huey Lewis put it, "It might just save your life...!"
