Really sorry if i am utterly wrong. No offence please 
From the eye of a Poly student, JC students are proud and are only
good at studying and lack the skill to survive in the world out
there.
From the eye of a JC student, Poly students are just sour grapes
and only knows how to compare their little strength with other's
flaws.
This is the world, people are all kind and yet selfish at heart.
Without kindness, one will definately not survive in this world.
Without selfishness, living has then lost its purpose. Man live to
find happiness. What is needed be done is finding a balance between
the 2.
Imagine a world that is perfect. Totally perfect. 100% happiness
with nothing needed be done. What is the purpose of living
then?
Whether it is God's will that ppl are put through challenges, or
from a freethinker's (me) view, that challenges is what gives life
meaning, a totally perfect world is definately not desireable to
live in.
