When he delivered they said, what about another 5. Then it was come back in the morning with 10 more. When he delivered 10 they said, "why not 11?" Then he got it. Kaizen is not just taking millions of little steps, it is not just doing it because the boss says so, it is not even because you take pride in your work and you want to do the best job you can, its because you do everything with your customers and their needs in mind.
I really like how the idea of always looking to improve was presented here: Kaizen Means Thinking "Now Things are the Worst Ever":
It is difficult to do this in an organization that has not accepted lean principles. You have to be careful to not be seen as negative and just focusing on problems when so many others are trying to cover up problems and focus on what makes them look good (they have to think about their next performance appraisal after all).
