About knowledge, who is clever and who is fool

      Anybody is fool, because noone is know everything  about god create in this world.
If one doctor health, medical  learn about human body , he maybe do not learn about how to build a bulding.
     We must always learn about something new, always learn, search a knowledge for ourself so its also brndfit to us,(also not easy to cheat by someone)
    We maybe clever about something we read, learn but maybe we fool about something we do not read or learn.
     So we better do not proud what's already we have, we know, we learn cause noone is know everything thats tbing exit in this word.
