If no one ever questions your entrepreneurial approach, you are doing something wrong.
In business especially, no one is infallible. And in startups, you can only benefit from asking for opinions from people you trust and respect. (Whether you listen to those opinions or not is another issue.)
Ben Parr, co-founder of DominateFund, explains that your reaction to criticism matters more than the criticism itself. An investor or advisor just wants to hear that you are listening and processing their advice, so choose your words carefully.
