Your business is your business, so don’t be shy about protecting it from inquisitive friends and family. They may mean well when they offer unsolicited advice, but there is no law saying you should take it. Listen to what they say, add a grain of salt, then take it or don’t. There could be value in what they say, but it could also just be a lot of noise. They see things from their perspective, and they have their own agenda. They don’t know what it’s like to live your life.
