The true crossroads of knowledge begins with oneself, this the ancient Greeks already knew very well. To be truly wise we must comprehend and understand the limitations of our knowledge, know ourselves as ignorant to begin knowing. The opposite of this is known as the Socratic ignorance: to believe that we know something when we really do not have the slightest idea that we do not know anything, is to believe that we know. So what remains is to submit ourselves to a constant introspection to 'know ourselves' and thus help others achieve the same.
