I send out lives right away as they are asked of me. But I receive very few back. Why?

How is it I send many lives immediately after being asked. Yet I receive very few. Is there something I need to do to make it better.  And I also have difficulty navigating this community thing. Any tips?

Am I doing something wrong?
