A staircases life

Nowadays,we will always think that,in our life,we should always look forward and fight for our future,but sometime,when you slow down your footstep and look back what had you done,you might discover something special =)
This is the story about a staircase life..
Long long time ago,there was one pair of couple,they live at 80th floor.One day,they went for a jog,when they reached home,they realised the building was ran out of electricity,they carried loads of stuff and sweat like a dog,so they actually rushing back home for shower.Therefore,the wife suggested that they took the stairs and no need to wait for the lift.Well,the husband also agree with it.In the end,both of them took the staircases.But when reach 20th floor,the husband suggested that they leave their stuff at there and when everything is back to normal,they just take the lift and go down to get back their stuff.The wife smile and agree with her husband,hence they took out everything and left it at 20th floor.After that,they continued to walk the staircases,but at the moment they reached 40th floor,they already exhausted and there were still 40 more floor to go..and they started to blame on each other and quarrel..Slowly,they reached 60th floor.At that moment,they were completely enervated and dont even have the energy to quarrel anymore..So the husband said.'let's stoped blaming on each other and continue walked for the last 20 floors.'..Eventually,they reached their home.Suddenly,the wife realised that she had left the key in her haversack that they left it at 20th floor.
Some people said that this story is actually describing our life.Before we reach age 20,we all are live in the world that protected by our parents and work hard to fullfill our parents' and teachers' hope,it's just like carrying a big and heavy haversack.After 20years old,we are set free and we start to enjoy our life.But when the moment we reach 40 years old,we were mutters that life is sucks,we start to moan that everything in our life,for instance,life,work,family,working partner or place,salary etc.Till we reach age 60,we start to regret what had we done in our pass..therefore,we start to console ourself,stop complaining about life and learn to appreciate what we own.By the time we reach 80 years old,it seem like we already walk til the end of the bridge,we start to look back our life and realise that we never accomplish our dream and it still stuck at the age we were 20years old.
The moral value of this story is..we should learn to achieve our dreams so that we wouldnt remorse when we come to the end of our life =)
So,buck up!!and learn to appreciate every moments that u spend in ur life <3
