Go jogging or go to the gym-you'll look better and feel better. Your actions will likely make you more attractive/marketable, to others, you're more likely to get out and meet new and different people, and you'll be happier and better suited for a lasting relationship. Instead of spending an hour a day, surfing dating sites and answering emails from prospective suitors, spend that time improving your own life.
Instead, work on improving yourself, and things are more likely to happen. Even if you're lonely and want someone to share your life with, don't be so proactive about looking. Nonetheless, I'll give you the same advice I give everyone else who has ever asked me: Don't look. There are billions of people in the world, and none of them have been able to answer this question, yet.
