sop for life... can we define it??

                      
when i was a kid i wanted to be painter, when i voluntarily provided acupuncture massage  to my mum she wanted me  to be a physiotherapist, when i grew up n read about the respect given to professionally qualified ones.... i wanted  to be an engineer, in mid way of engineering a storm of monetary greed hit me and i wanted  to be rich , now that i am an engineer stabbed by the reality behind it.... i want my childhood creativity back.... so i want to be a painter..... lol! no wonder they say world is  round.....but  then this clearly states  how vision changes
well such is life dearies at times..... you really spend your entire  life  trying to figure out  what exactly u want out of it.. n all u see is.. its always  life  getting  out something  from you. people say define your path..... but can we really define  our  path? how many  times  have you been asked in an interview  to define your  life path ?  i mean quite a lot of times.... be it  universities, be it colleges , be it job...people  sometimes  get down to asking u to pen down the years and  the position u would  uphold  at that time.... but tell me one thing  if  we could  pen down that and  it all tends  to be true.. then m sure  it wont  be difficult for us  to pen down our  death date as well... isn't it?coz den this is  also a milestone  rather  the last milestone  of our  life... but somehow  then we afford  to choose a safe answer- life  is unpredictable, haah! when its  unpredictable, den y r we asked to predict it? isn't it  a weird  irony ?  i do not  say that my case  is a perfect reason for me to argue..  u can call me  indecisive, or fickle minded.... but then it subtly specifies.. that with time  and with age  priorities  change.... so if a person at present  wishes  to be  a rich... doesn't mean he would  be want the same  10 yrs  later..  if  a person wants to own a firm at present... doesn't mean he would never agree to a become CEO for someone else's  firm...
so tell me can we really define  our  vision ? can we really pen down  our life path... n even if  we do... will it always hold truth? think about it....
