by professional, I am a BA, so a lot of time I spent time defining a concept, a problem. Getting the essence is critical in communication. The best way of defining something is (in my opinion) A is kind of B with some specific attributes or fact of A. B is either an analogy used or a super type of A. Ask yourself this question, what is A, is it kind of something else or does it look like something else? to illustrate your idea, give some examples or even non-examples.

recommended reading: a book called Made to Stick, it talks about the SUCCESS principles, Simple, Unexpected, Concrete Concise, Emotion, Specific and Story.

I enjoy your posts, keep posting good stuff:)
