A strong personality from 2 "a" (1984)

Once a second-grader Dima Kruglikov learned that all the great people became so because they did not waste time on trifles, they had a clear regime of the day. Wishing to become great, Dima decided to live on schedule: to walk, help his grandmother, and even make friends. Getting into ridiculous and absurd situations, the main character of the film realized that the regime of the day is important, but everything must be done wisely.
