I remember when I was doing fulltime book distribution, there was a time when we felt that we even had to distribute on Sundays for a few hours, no matter what, just so that we wouldn't lose momentum from taking one day a week off. It's not that I'm recommending that this policy be adopted. It's important to get at least one full day for rest and extra study when performing fulltime book distribution. However, in principle, a dedicated book distributor should know that any time not spent on Sankirtan should be used to increase his determination and enthusiasm for Sankirtan. That service requires that kind of resolute determination.
