Make them excited about the thing you are building. Especially telling about the possibilities of the thing you are building and how it can actually help people by giving concrete examples. This is just my personal view. I don't prefer people who use abstract and hand wavy vocabulary to discuss their vision and ideas as that just means you don't have enough clarity of thoughts yet.
