They are Interested in Results. They are always working on something New and Exciting. Wizards are very clever and skillful. They love science, but have a different mind set than scientists. Scientists want to have an explanation, a reason for everything before they publish their data.
Wizards are a lot like engineers.
Engineers are dooers too, but most are content to work within the narrow limits of their charts and graphs. A Wizard can't stand limits. He always wants to expand his boundries, discover new possibilities, do new things. You say a Wizard is an inventor then. Most inventors are working to find new things to patent.
