We can't care more than the customer

Passion for what you do, and a level of expertise in how to get it done right can be a great frustration when the customer doesn't agree with you or asks for something different

It might be the color palette, the word choice, layout, timeline or anything else, and YOU know that it's not the best way to do it

But the customer wants what they want, and provided it's not illegal or life endangering we can give them what they want

And time after time I've heard people say, "we can't care more than the customer"

But we can care less

How do you deal with a customer that wants what you know isn't what they need?
