Referring people is a science, not just luck. Many say all you need to do is post your links and banners all over, but I can tell you there is a lot more you can do to get serious numbers like I do. The basic concept is to establish and cultivate trust, then present it in such a way they can see themselves doing it. It also helps if you combine it with other money making activities so the potential increases. Don't kid yourself, there are MILLIONS of people from the USA and Canada that are looking every day for ways to make more money online, you just need to get in front of them with the right message.
