“  When you  want something , all the universe conspires in helping you  to  achieve  it.”

                                                                                – Paulo  Coelho


WBCSis  not  just an exam but  it is a dream ! To achieve  this dream I have  followed  the three Ds   –  Dedication    Discipline   Determination.

So many people fail to crack the  civil service exam ( State PSC/UPSC ) not because they do not have the ability but because they do not have the HEART to go through adversity.  When you are in darkness you wait and sit for light to come from some where,  BUT   you cannot simply wait ,  the only way out is to step forward and face your fear  and  BECOME YOUR  OWN LIGHT !

Turn every  OBSTACLE into OPPORTUNITY !  Remember success don’t teach us anything , it is our failures that removes the rust with in us, turns us from IRON  to GOLD!

S  Aggarwal  will  work  wonder !   The  key  to  ace  this section  is  PRACTISING   keeping  in  mind  SPECIAL  NUMERICAL  TYPES .   Pay  extreme  attention  to  SHORT CUTS involved.  Let  me  explain  with  few  examples :-

“There is a higher court than courts of justice and that is the court of conscience. It supersedes all other courts.”

 -Mahatma Gandhi 

Don’t ever give up on yourself!  I  must  admit  that fear and failure are my  friends. They knock me down on my knees and from there my growth starts like  a“phoenix bird  who  rises again from the ashes”.   Like  our  muscles grow , when we strain our muscles in gym  similarly  we as an individual  will also grow when we  strain our selves and endure  tough times !  I repeat  that  examinations like WBCS is not just another exam but  a  process  through which  we  ultimately  learn  , imbibe and acquire  leadership and a plethora of other positive qualities.

The rigors of  this demanding exam enlightens us from within , so that we become  real leaders  and  serve our motherland  with   honesty , integrity , zest and enthusiasm!  During your preparation phase you must  put in all your efforts  and be true to your  conscience.  Take  ownership and LEAD TO VICTORY !

I will end  with abeautiful definition of  life from   Bhagavad  Gita:-


What is Life
Life is an Adventure … Dare it
Life is a Beauty … Praise it
Life is a Challenge … Meet it
Life is a Duty … Perform it
Life is a Love … Enjoy it
Life is a Tragedy … Face it
Life is a Struggle … Fight it
Life is a Promise … Fulfill it
Life is a Game … Play it
Life is a Gift … Accept it
Life is a Journey … Complete it
Life is a Mystery … Unfold it
Life is a Goal … Achieve it
Life is an Opportunity … Take it
Life is a Puzzle … Solve it
Life is a Song … Sing it
Life is a Sorrow … Overcome it
Life is a Spirit … Realize it
The Bhagavad Gita
