This is true. All of these quests and adventures are supposed to be dropped in Link's lap. I have seen nothing in his character to make him venture out into the world, and raid temples and dungeons. However Link is also supposed to be completely willing to take up these tasks, even though it puts him in danger.

As far as a love interest goes....Link should not be a pimp or anything. Having a few girls in his village express interest in him, while he is very casual about everything sounds like it would fit Link well.
