If you know everything about a subject at least you know you surely know little about it. As you know, the more you know about something the more you know what you don’t know. This can leave you knowing so much you end up knowing relatively nothing. Knowing of this phenomenon should encourage efficient and relevant knowledge acquisition. Get to know your gaps but also know more detailed and fundamental information about how and why the things you know work. Then when you know more you know what you need to know most and you know how to tell if what others know and how to help them know better or how to get them to help you know better.
Do you know what you don’t know?
And remember: Knowing is growing and sharing is caring, so share your growing knowledge with care and know someone will do the same.
