Agreed. Life in general is sales. Job interview? Sales. First date? Sales. Sales is more than "Here's my product/service. Give me money". It's the art of getting someone to do what you want. I can only speak to American culture, but I feel like most people feel icky about that because the first thought that comes to their mind is the car dealership guy that's trying to sell you garbage like gap insurance that you don't need. Kind of like networking, it feels by definition manipulative when it doesn't have to be.
