According to the text, how much do people remember of what they do?

The statement that people remember about 90% of what they do is rooted in the idea of experiential learning, which emphasizes that engagement in an activity significantly enhances retention and recall. This high percentage reflects how hands-on involvement enables individuals to process information more deeply, leading to better memory formation. When people participate actively in their learning, whether through practice, teaching others, or applying concepts in real-world scenarios, they reinforce their understanding and enhance their ability to remember that information later.

In a hospitality context, for example, when employees are engaged in training through simulations, role-playing, or actual service scenarios, they are much more likely to retain that knowledge and apply it effectively in their jobs. This approach contrasts with passive learning methods, such as listening to a lecture or reading, which tend to result in significantly lower retention rates. The emphasis on "doing" not only improves memory but also builds confidence and competence in applying skills, which is critical in the fast-paced hospitality environment.
