As a humble human being, I think we should all listen to opinions from our family and friends.
However, when doing what I believe in at work, I think it is important to sort out the opinions that really matters. Listening to too much/wrong opinions at work (on the project you are working on / developing) can sometimes be the worst thing.
Imagine if Apple had listened to what everyone had to say before launching iphone. It would have been a colossal mistake!
Sometimes, it is better to make a mistake doing what you truly believe in than to make a mistake following someone else’s opinion.
