This one might be a challenge for some - and I don't blame you. Our hearts and minds have been set in ways that sometimes we don't even realize. But to get the absolute most out of experiences and life in general learning an appreciation for the unexpected is helpful.
To have an open mind means to be willing to consider, entertain, and even implement new and diverse concepts without prejudice. It means being receptive to a wide variety of viewpoints, information and ideas especially when they do not match your own.
