With the greatest respect, my life experience has taught me how powerful and important attitude are. The more a person convinces themselves of the truthfulness of something, the more it becomes reality. Joe has fantastic advice, and I agree that doing things to make yourself happier that aren't focused on love itself will definitely help. If you shift your own focus, and cease thinking that nobody will ever love you, I think that you'll not only enjoy your own chosen activities more, but will begin to draw the interest of others, and love will develop naturally on its own.
Kind regards,
