Helena CEO of a Private Company with Approximately Fifty Employees. Mostly Red, Without Any Green or Blue. A Small Dab of Yellow. What do you think of this tool? DISC language? I think it seems to be an effective way to avoid misunderstandings. I understood immediately what it was all about, so I think the book could have been shorter—half as long, maybe. I would have concentrated the text more. I don’t like repetition. But sure, it’s a useful tool. Last Christmas I gave a copy to all my coworkers as a gift and asked that they read it. And almost everybody did.
