The creative business is full of bright people with opinions. And therein lies the rub. A lot of voices yelling at the same time isn’t about finding the right idea, but about putting pressure and distractions on the poor person whose job it is to find the right idea and deliver it.
In the end there is one person in charge of, and ultimately responsible for, delivering a great idea. If you’re not that person, then let that person try to find the truth. Remember, there’s no shortage of people willing to blab out what they think is right. There’s only one person, in the end, responsible for making sure.
Give that person the space to get it right. Get out of the way. Pick your moment to be heard, carefully.
