Lets cheer about something!

Dear friends,
We get up early in the morning n pick up the newspaper n within minutes our face starts contorting because we see so many disturbing news headlines...bomb blasts, crimes, dirty game of politics and instantly it creates a kind of sadness in our psyche...so what should we do...how to overcome that inevitable sadness? Any answer?
I think the answer lies within...just get up and do atleast one positive thing to better the society...it will surely cheer u up...world is still a better place n we have to believe in ourseleves that when we leave this mother earth...the next generation would be smiling at our efforts! Amin.
