Out society is not the same as what we imagine at our pure school time,there is something change even though it's not our willing to be,it really changed and continue to.
There are so much unfair things around us,it make us feel disappointed even despairing,it's so cruel.
So sometimes yearning for the time which went away.But something went away never come again.
What we can do just face to the fact in a optimistical way and don't give up our dream and keep on pursuing.
Unfair things exist here and there,maybe we are not so great to change it,but we can adjust our attitude to fight for the better future.
Don't be afraid even though there is so much obstacle in the way.
Improve oneself continuously.
