A learned man once visited an Indian temple under construction where he saw a talented Indian sculptor making an idol of Shivalinga. Then to his surprise, he noticed a similar idol lying nearby.
Surprised, he asked the sculptor, "Do you need two statues of the same idol?"
"No," said the sculptor without looking up, "We need only one, but the first one got damaged at the last stage."
The gentleman examined the idol and found no apparent damage. "Where is the damage?" he asked.
"There is a scratch on the Trishul of the idol." said the sculptor, still busy with his work.
"Where are you going to install the idol?"
The sculptor replied that it would be installed on the Dwajasthamba - a pillar twenty feet high.
"If the idol is that far, who is going to know that there is a scratch on the Trishul?" the gentleman asked.
The sculptor stopped his work, looked up at the gentleman, smiled and said, "I will know it."
The desire to excel is exclusive of the fact whether someone else appreciates it or not. "Excellence" is a drive from inside, not outside.
Excellence is not for someone else to notice but for your own satisfaction.
