It is also a good habit to be determined that we will not do anything else in the day until we have completed our japa quota. Not finishing all our rounds in a sitting should be the exception rather than the rule. Some people’s work schedules may make such a thing impossible, but we should chant as many rounds at one time as we can, and in the case of the person with the job, the rest of the rounds should be completed when he or she returns from work in the evening.
