'But How Do You Know?'

So ask yourself these questions.

Do you like it?
Your answer to that question, whatever your personal reaction is, should always be, “It doesn’t matter if I like it.” Like is irrelevant — you can love a piece of creative or a concept more than you love your own children, but that doesn’t mean it will work. You’re not mailing a 10,000-piece test to yourself, so how you would respond personally shouldn’t be a factor in whether or not to green-light it.
