What you do not know?
In the internet world with social media, it is hard to not know anything in general.
Even if you mute news, news still come to you through people's talking.
We have all became generalist.
And the more we generalize, the harder we specify.
We are supposed to stop bragging how well that we know something generally and begin to humbly learn something specifically.
Today, we need no more information anymore. No excessive information means no distraction, no unnecessary interpretation and process of information.
So instead of asking "what do you know?" We should start asking "What you do not know?"
Limit information that comes to you. What you do not know defines how well you can devour time knowing something specifically within your field.
So tell me, What you do not know?
