Comparative & Absolute Advantage

A person has a comparative advantage at producing something if he can produce it at lower cost than anyone else.
Someone has an absolute advantage when they are the best at doing something.
Someone does not automatically have a comparative advantage when they have an absolute advantage. This is because a person might have an absolute advantage in doing a number of different things - however, while they are actively engaged in one thing, they are giving up time they could be spending doing something else that they may also have a comparative advantage in. This means that they have to determine the opportunity cost - the difference in value between producing one thing over another.
Everyone has a comparative advantage at producing something. Everyone has something that they can do that will allow other people to do something else that they do better. So even if you are the worst at something, there will be someone out there that still will make gains by having you do that thing, while they do something else. The essence of this is about specialization. If you specialize in something you get very good at it and it is better for you to stick with your speciality and buy other needs, than to try to do everything yourself as a generalist.
