Compose an essay.Many people envy others' possessions or status instead of cherishing their own, as described in the saying "The grass is always greener on the other side." What do you think of it? Write a 300-word expository essay to express your opinion in this respect.
     AS AN OLD SAYING GOES, "THE GRASS IS ALWAYS GREENER ON THE OTHER SIDE." IT HAS THE MEANING OF BEING AMBITIOUS AND GREEDY. NOW, I WANT TO GIVE IT A NEW EXPLANATION, AND VICE VERSA, IT SHOULD BE THE SPIRITUAL REALM PURSUED BY EVERYONE.
     LIFE TELLS US THAT IN ORDER TO ACHIEVE A GREAT CAREER, ONE MUST HAVE THE SPIRIT OF AMBITION, UNREMITTING PURSUIT AND NEVER GIVING UP. PEOPLE CANNOT LIVE WITHOUT THIS SPIRITUAL BELIEF, JUST AS BIRDS CANNOT LIVE WITHOUT WINGS THAT FLY, AND FISH CANNOT LIVE WITHOUT GILLS THAT FILTER WATER AND OUTPUT OXYGEN.
     "THE GRASS IS ALWAYS GREENER ON THE OTHER SIDE" IS A KIND OF SPIRIT THAT WILL NEVER BE SATISFIED. PELE DID NOT KNOW HOW MANY GOOD GOALS HE SCORED. HIS SUPERB SKILLS NOT ONLY INTOXICATED THOUSANDS OF FANS, BUT ALSO AMAZED THE AUDIENCE. WHEN SOMEONE ASKED HIM, "WHICH GOAL DID YOU PLAY BEST?" HE REPLIED WITHOUT HESITATION: "THE NEXT!" IF HE IS WILLING TO ACCEPT THE STATUS QUO AND ARE EASILY SATISFIED, HOW CAN HE ACHIEVE OUTSTANDING RESULTS?
     "THE GRASS IS ALWAYS GREENER ON THE OTHER SIDE" IS A SPIRIT OF KEEPING IMPROVING. "NOT FOR THE BEST, JUST FOR THE BETTER." IT HAS BECOME THE MOTTO OF SOME PEOPLE, EXPRESSING THIS IDEAL OF PURSUING PERFECTION. LEONARDO DA VINCI, A PAINTER WHO HAS MADE GREAT CONTRIBUTIONS TO THE ART WORLD SO FAR, SPARED NO EXPENSE FOR ONE YEAR IN ORDER TO PAINT AN EGG WELL. LATER, MONA LISA'S SMILE TOOK HIM THREE YEARS. ALL THESE SHOWED THE SPIRIT OF KEEPING IMPROVING.
     "THE GRASS IS ALWAYS GREENER ON THE OTHER SIDE" IS A PIONEERING SPIRIT. GERMAN PHYSICIST EINSTEIN FINISHED AN ASSIGNMENT WHEN HE WAS IN PRIMARY SCHOOL — THE UGLIEST LITTLE BENCH. WHEN THE TEACHER SAID HE DID NOT DO WELL, HE TOOK OUT THE BENCHES HE HAD MADE THE PREVIOUS TWO TIMES AND COMPARED THEM. INDEED, THE THIRD ONE DID A LITTLE BETTER. IT WAS PRECISELY BECAUSE OF HIS ENTERPRISING SPIRIT THAT HE LATER PUT FORWARD HIS SPECIAL THEORY OF RELATIVITY, DENYING NEWTON'S ERRONEOUS THEORIES.
     TO SUM UP, EVERYONE HAS A DREAM NEED TO HOLDS THE SPIRIT OF "THE GRASS IS ALWAYS GREENER ON THE OTHER SIDE" AND PURSUE OUR BRIGHT FUTURE.
