Life in the society is always in a everchanging environment,
just like what is taught in school, how much will the knowledge be
applicable in real life. As everyday we spent on and worked in
life, we learnt something new. Knowledge can be imparted but
experiences can't. They have to be experienced in order to be
gained and applied to life.
It's up to the individuals to perceive these thoughts and never
think life's out there as good as it was in school. Think of it as
the school as the womb that encompassed us for at least a period of
time before we were borned into the world, once into the world, we
have to learn how to breathe, eat, crawl, walk and so on. Very much
like so in real life.
