Everyone need their interests, likes/dislikes, hobbies, views, e.t.c because it's these things that make us unique, it's hard to put down in words what you think you may be looking for in someone; because sometime you don't know what you are looking for until you stumble across it in the dark and stub your toes on it. Obviously you want to meet someone who has similar interest, hobbies, views e.t.c. so there is some compatibility.
