People like to say things like "nobody's opinion matters but your own."
In some cases, this is true.
But for the entrepreneur, or the business owner, opinions come in the polarizing form of online reviews. And reviews are the currency for success for businesses these days.
So I ask you to cater your advice in a way that makes most sense to the recipient. Perhaps they shouldn't care what people think about them, but it's integral to constantly consider what people think of their work.
