Why do we make unnecessary comparison?

A crow lived in the forest and was absolutely satisfied in life.
But one day he saw a swan. “This swan is so white,” he
thought, ” and I am so black.

This swan must be the happiest bird in the world.”

He expressed his thoughts to the swan. “Actually,” the swan
replied, “I was feeling that I was the happiest bird around
until I saw a parrot, which has two colors. I now think the
parrot is the happiest bird in creation.”

The crow then approached the parrot. The parrot explained,
“I lived a very happy life until I saw a peacock. I have only
two colors, but the peacock has multiple colors.”

The crow then visited a peacock in the zoo and saw that
hundreds of people had gathered to see him.

After the people had left, the crow approached the peacock.
“Dear peacock,” the crow said, “You are so beautiful. Every
day thousands of people come to see you. When people see
me, they immediately scare me away. I think you are the
happiest bird on the planet.”

The peacock replied, “I always thought that I was the most
beautiful and happy bird on the planet. But because of my
beauty, I am entrapped in this zoo.
I have examined the zoo very carefully, and I have realized
that the crow is the only bird not kept in a cage. So for past
few days I have been thinking that if I were a crow, I could
happily roam everywhere.”

That’s our problem too.
We make unnecessary comparison with others and become sad.
We don’t value what has God given us. This all leads to the vicious cycle of unhappiness !!!
