If they're ivars (attr_accessible), then just use the ivar itself. If they
are methods on the class, then you'll need the self for there reason you
mentioned:

def initialize(attributes =3D nil)

  super  # If exact signature, don't need arguments

  @step                =3D 0

  @national_debt       =3D 0

  @sum_of_income       =3D 0

  @sum_of_taxes        =3D 0

  @sum_of_happiness    =3D 0

  @sum_of_investments  =3D 0
end

Oh, and you never need to return anything from #initialize.
