Love = Wine ??

There a tagline of an old movie that caught my attention. It says 'love is like a wine, a little to make you happy, too much will make a fool'. Its very true. I've heard, seen, read, talk with and know about peoples doing stupid things for love. I wonder why it have to be that way? I recalled one of the dialogue in a tv series about a guy who do smart move in his life and successfully changed his life but the other guy said that yes, you're successful but i didn't see you wearing a ring. Dude, you're lonely. Smart = lonely. Fool = love. Which one you will choose? I always go for love. It can be fool, or even try to be in love in smart rational way. In the end, what matters is whether you're happy or not. Right?
