14. Don’t say: “How about we just go back to your original concept?”

Why? Designers are designers because they have the artistic and technical ability to do their job well. Sometimes instead of asking for multiple iterations of a design concept, it’s best to trust your designer. After you explain what you need, let the designer come up with the best design she can. Then, take a good, hard look at the design — maybe take a couple days to mull it over, or run it by a trusted third-party who has some knowledge of design or your industry — and make sure any changes you request are necessary and explainable. Don’t waste your designer’s time with endless experimentation when the initial design is exactly what you asked for.
