You can literally spend your entire life just reading and it still won’t be enough. People devote years of their lifetime just to study small parts of text they consider to be holy. People spend a lifetime reading about science and the universe. People spend a lifetime reading about psychology and trying to understand how humans behave. People spend a lifetime reading about history, politics, economics, philosophy, education and technology. So if you ever feel like you know enough then you’re very mistaken. There is an infinite amount of reading one could do and there is an infinite amount of questioning one could do, for that is how we truly grow as individuals and as societies. Now, some people enjoy reading books, others (including myself) may find it difficult to concentrate when reading full books. But there’s always something to read, could be the newspaper, could be an article online, just anything.
