Wanna to share a nice thought which I came across recently.

The concept has been illustrated with the beautiful story.

Two men, both seriously ill, occupied the same hospital room.  One man was allowed to sit up in his bed for an hour each afternoon to help drain the fluid from his lungs. His bed was next to the room's only window.   The other man had to spend all his time flat on his back.

The
men talked for hours on end. They spoke of their wives and families,
their homes, their jobs, their involvement in the military service,
where they had been on vacation.  Every afternoon when the
man in the bed by the window could sit up, he would pass the time by
describing to his roommate all the things he could see outside the
window.

The man in the other bed began to live for those one
hour periods where his world would be broadened and enlivened by all
the activity and color of the world outside.  The window
overlooked a park with a lovely lake. Ducks and swans played on the
water while children sailed their model boats. Young lovers walked arm
in arm amidst flowers of every color and a fine view of the city
skyline could be seen in the distance.

As the man by the
window described all this in exquisite detail, the man on the other
side of the room would close his eyes and imagine the picturesque scene.  One warm afternoon the man by the window described a parade passing by.  Although
the other man couldn't hear the band - he could see it. In his mind's
eye as the gentleman by the window portrayed it with descriptive words.

Days and weeks passed.  One
morning, the day nurse arrived to bring water for their baths only to
find the lifeless body of  the man by the window, who had died
peacefully in his sleep. She was saddened and called the hospital
attendants to take the body away.  As soon as it seemed
appropriate, the other man asked if he could be moved next to the
window. The nurse was happy to make the switch, and after making sure
he was comfortable, she left him alone.

Slowly, painfully,
he propped himself up on one elbow to take his first look at the real
world outside. He strained to slowly turn to look out the window beside
the bed.  It faced a blank wall.

The man asked the
nurse what could have compelled his deceased roommate who had described
such wonderful things outside this window.  The nurse responded that the man was blind and could not even see the wall.  She said, "Perhaps he just wanted to encourage you."

Epilogue:
There is tremendous happiness in making others happy, despite our own situations.  Shared grief is half the sorrow, but happiness when shared, is doubled.  If you want to feel rich, just count all the things you have that money can't buy.
