I'd have to say it's true. For one thing, none of the relationships I've ever been involved with were a result of my trying to find someone. They quite literally came to me.
Second, a few years ago I was actively trying to find someone. I joined online dating services, went out a lot, went to parties and gatherings, etc. When it was said and done, after 6 months of effort, I was still alone. Two weeks after I stopped trying, however, I met someone that I ended up having a 3 year relationship with.
