We propose a new measure for eternal inflation. We require that both conditions, large field fluctuations and smooth homogeneous domains be included in the probability estimate in order to produce successful inflationary pockets. We show that due to the increasing inhomogeneities in the background spacetime fractal, self-reproductions stop within a finite time t(f), thus inflation cannot be eternal.
