You say that you want a relationship, but do your actions match your words? You may be so focused on your job or a favorite pastime that you aren't really devoting all that much time to looking for a mate. Perhaps it has something to do with your love of control.
At work, you're in command. On the dating scene, who knows what could happen! Or you're so involved in rewriting your latest report that you don't even come up for air until midnight.
Redirect some of that passion, determination, and effort to looking for love! After all, what are you working so hard for if you can't have some fun?
