We don't listen to opinions so that we can change to impress others. We listen to other opinions because there are a lot of things that we can learn from them.

By not listening to others' opinions and just believing in what we think is real, we can limit our walks in life. I also believe that whatever we do in our lives doesn't just pop out of our head; somebody else has given us that idea.

Lastly, of course, we should filter every opinion we get before accepting it.
