Is it really?

I am one of these sentimental girls who subscribe to the Google Love Quote of the Day, & this afternoon when I opened up my Google page I read:  

"Love is everything it's cracked up to be. That's why people are so cynical about it... It really is worth fighting for, risking everything for. And the trouble is, if you don't risk everything, you risk even more." Erica Jong  

What I want to know is, having never been in love myself, is it really?
