Most people like to think that they are right. When someone comes along and tells them otherwise, they tend to ignore what that person has to say. That is called ignorance. Oftentimes it takes an outsider to see the problems that insiders may have missed, so I think it’s wise to always be open to suggestions. You should take the time to actually listen to what other people have to say, because they may have seen something that you missed by being in an environment for too long.
Sometimes people become too fixed on doing something one way, and they fail to see the fact that there’s a better way to do it. There is nothing wrong with that. However, I really dislike it when they still continue to stubbornly do what they’ve been doing all along even after being given a suggestion. They do not even consider the other option, and they blatantly continue to believe that their way is the only right way to go about doing things.
All I can say to those people is: it’s your loss. The person giving you the suggestion is actually doing you a favour by telling you what you can improve on. They could have just let you continue doing whatever you were doing, but instead they took the time to offer you a suggestion. When someone gives you a suggestion and you refuse to even consider it, you have just closed a door that could potentially improve your way of life. I believe that suggestions should be patiently listened to and thoughtfully considered. It really isn’t that hard to do, and you’ll be glad you did it!
