At the end of the day, what ever product you sell or service you provide, you are selling an emotion.
Apple is a great example of this. You are emotionally sold when you open their deliberate packaging. When you interact with their friendly software. When your problems are solved at the Genius Bar. You get to experience wonderful emotions over and over.
If you are a consultant you sell emotion through your integrity, when you show up early, or fished a project under budget. These are all emotional wins and you are selling them constantly.
Saving someone money. Making someone money. Offloading work for someone. A firm handshake. Listening with intent. These are all emotional wins.
It is you job to find all the places and moments in time where you can provide emotional wins.
