It is not the quantity but the quality of knowledge which determines the mind’s dignity.

Collecting facts is easy now, and a head full of trivia can look impressive while understanding very little. What gives a mind its worth is the kind of knowledge it holds: whether it grasps why things are so, whether its ideas connect to each other, whether they bear on how to live. A few things truly understood can outweigh a library skimmed.

Consider what you have been learning lately, and whether it is going wide or deep. Choose one subject you care about and give it slow attention for a while, reading one good book twice instead of five summaries once.
