If you are uncomfortable, dissatisfied, disappointed in your products and services, you may be an innovator. Of course, you may simply be a curmudgeon, never happy with anything, but that will be evident to everyone around you. The difference between curmudgeons and innovators is often subtle, but it deals with the difference between simply complaining, and acting on your passion. Innovators are frequently dissatisfied, but are simultaneously seeking new and better solutions. As Emerson wrote, "The reasonable man adapts himself to the conditions that surround him... The unreasonable man adapts surrounding conditions to himself... All progress depends on the unreasonable man."
