If you ask someone to give you feedback on your business idea, make sure they actually understand what you are trying to do.
Granted, that’s your job — to make it clear and simple.
But be careful to take feedback from someone who sees a limited scope of your vision. You may have a winner, only to abandon it because someone with a strong opinion shot your idea down … but actually didn’t understand it. And even if they did understand it, that’s just one person.
Listen to the market of consumers.
