Discussion on cosmic ray propagation in the Galaxy is presented. The principal topics are the following: parameters of the basic diffusion model, possible role of convective (wind) transport, effect of distributed reacceleration, radioactive secondaries in cosmic rays, truncation of path length distribution in cloudy interstellar medium, dependence of diffusion on energy and anisotropy constraints.
