Why I am not studying??? 
Because : 
 
No Study = Fail ....................... ( I ) 
 
Study = No Fail ...................... ( II ) 
 
By Combining ( I ) & ( II ) : 
 
===== ( No Study + Study ) = ( No Fail + Fail ) 
 
By Taking ( Study ) as a common factor in the left hand side 
And Taking ( Fail ) as a common factor in the right hand side 
 
===== Study ( No + 1) = Fail (No + 1 ) 
 
By Dividing both sides by ( No + 1) 
 
===== Study = Fail 
 
SO I ADVISE YOU TO STOP STUDING
