The guy that knows and the guy that does not….
There is nothing wrong about not knowing!
A brain surgeon may know nothing about the Aztec origins…. A NASA scientist may not be the best at accounting and filing his taxes! They are smart guys none-the-less and you can play their history teacher or the CPA as long as they acknowledge that they are lacking in those skills.
Acknowledgement and humility in the knowledge of what one knows and what one does not, pays!!!
Stop assuming that you know more than you actually do… stop pretending like you do!
Let not anyone take away the fact that you know what you know… By the same token, do not try discounting what the other person knows…. lest, you reveal yourself as the guy the guy that does not!!!
