Scope for improvement - A different perspective

Being in software engineer's shoes, one is supposed to get acquainted with the typical Jargon of the day to day life. One of the few things which bemused me the most are the words "There is still a scope for improvement". Bosss do you know the exact definition of perfection??? I wonder if there is anything in this world which is absolutely perfect and leaves no scope for fault finders... I sometimes feel the main driving force behind these WORDS of WISDOM is GREED ....This reminds me of an anecdote.. Once Mr X. had to go to a place by 10:30 A.M. sharp. He had no other means apart from catching a bus. Here goes the chronological sequence of events....
First Wish : Bus to come early on time - bus comes
next --> Hope to alteast get a foot space on the foot board -- He hardly manages to get one
next --> Kaash Bus ke Andar jagah miltha --- Luckily he gets space and goes inside the bus
next --> Why is that school boy sitting the Raja way?? Why can't he share his seat???--- seeing his plight the school boy offers to share the seat...
next --> It is a bit clumsy out here.. why doesn't he alight the bus so that I can sit comfortably--- Thank God his school arrived .. He got to sit comfortably.. (Did I say comfortably???)
Next --> wish for window
next --> wish for a beautiful girl to sit beside him.......
His greed knew no bounds....
Are you not comfortable with what you have??? Are you not satisified enough???
There is always a scope for improvement... Should some lame person who is not even remotely related to us tell that to us?? Are we not wise enough to know that there is scope for improvement.... It seems as though they are the so called perfectionists and purists and we are their disciples...It is not only in this hyped software profession but it is the buzz word everywhere...They feel this is the most euphemistic way of expressing displeasure...They also sometimes say this even if some one performs splendidly lest he gets carried away...Even if you reach the pinnacle of success they still say "There is still a scope for improvement..."
Just Imagine if everything on this earth is put into objective terms......
