Everybody knows that ,

 

 If we will study we will not fail and if we will not study we will fail.

Keeping this in mind ,

PROVE-

If we will study we will fail !

GIVEN:    STUDY                            =       DON'T FAIL

                  DON'T STUDY               =        FAIL

TO PROVE:    STUDY                    =        FAIL

 PROOF:           STUDY                   =        DON'T FAIL         (GIVEN)                           ..............(1)

                          DON'T STUDY       =        FAIL                      (GIVEN)                           ..............(2)

                                      

                                             ADD (1) AND (2)

          STUDY + DON'T STUDY      =      DON'T FAIL + FAIL

            STUDY   ( 1 + DON'T )        =       FAIL  ( DON'T + 1 )

                                       STUDY      =       FAIL

                                                                    HENCE PROVED

 

 SO , DON'T STUDY VERY MUCH BECAUSE IF YOU WILL STUDY MORE , YOU WILL FAIL .  

NOTE:      Don't follow the above Theorem blindly , conditions apply.
