When someone asks you what you do, what do you say? People tend to give a top-level answer. They say, "I'm a lawyer, a real estate agent, a fitness trainer". And while that information is descriptive, it's also extremely vague. It doesn't necessarily get clients to want to work with you right away and often they're not curious enough to ask for more information. How do you avoid being vague? You do so with the power of subsets. Subsets allow you to be extremely precise and in turn make the client want to know more, thus increasing the chances of working with you. Best of all, creating a subset is easy. Time to figure out how to create a subset and use it to your advantage, eh?
