How many times have you met someone that is close minded. It is so frustrating! They don't listen to anything that you tell them, because they believe they are right 100% of the time. Many of my friends are like this, don't get me wrong, they are smart people, but they will often never listen to something that has to do with spirituality, or buddhism. Because of this they are losing out, on a huge wealth of knowledge.
Being open minded is easy, just think, that you can always gain something from what people say. Perhaps you could even reinforce your current view on an issue. Or because you are being open minded, you can learn the truth, then realize that being open minded, opens you up to so much more. Just think you are not always right, and people always know better. Listen, don't form judgements, don't say no. But think and contemplate, then you will realize so much more than you could have ever imagined.
