text: Another reason why you should listen to others opinions is because they can help with what you know and don't know. If you use snapchat, intagram, and facebook then you will most likely find an opinion in the first ten seconds that your in the app, this is because the app was designed to share someone's opinions with others. If you look on the app you probably find something new and interesting that could help you in the future whithout you even knowing that you got this skill from an opinion that was off of an app. These opinions are what give you knowledge, for example we started off as caveman but then someone came along and was like,"this is not good enough," and created a fire, then many other world changing opinions were expressed and that led us to this point in time now. To summerize it someone learned off of someone else and then that just kept happening millions of times and is still happening to this day with the ideas on how were going to put humans on Mars.
