How far would you go for happiness?

I have recently decided that I’m going to try to find one person out of the 6.8 billion in the world. I have his name, his photo, and one clue of where to start looking for him. It’s doubly hard because he’s not listed or even on the internet anymore. I’m going to spend time looking for him until I’m twenty. If I don’t find him by then, I’ll stop. Does this sound stupid..or do I sound very much in love with this person? Would you go this far for happiness?
