Value creation is when you put 1 unit in and get 2+ units out. When you put in a sketch and get a high fidelity rendering back out. When you give some feedback and the spirit of what you wanted is translated into a final product that is as good or better than you expected. When the questions get answered correctly before they get asked. When you can leave something with someone and it just gets solved with minimum fuss and frustration.
When you get fast-forwarded to the future.
