Answer:
This means that cleaning and organizing is something that needs to be done continuously since practice can pertain to an act that is customary or habitual, unlike project which only denotes something that is done periodically and usually requires time to be accomplished.
Explanation:
The 21/90 rule encourages everyone to do an advantageous task continuously for 21 days in order to create a habit. Doing it further for 90 days would lead for a person to develop a lifestyle. Therefore, I agree that cleaning and organizing should be a practice because these two, when done on a constant basis will lead to the development of desirable values--being clean and organized. It may be a long training, but it is worth it.
