#### 5.2.2 The Implementation of a Personalized Counseling Function for a Circular Lifestyle  
The circular lifestyle is a new and modern approach that includes management, increased efficiency, sustainability, new opportunities, responsible choices, and assumed behaviors. In this process, nothing is thrown away. Everything is reused. The original traditional model, which recommended that the consumer buy the product, use it, and throw it away if it is used or no longer meets the criteria of choice and use, is replaced by a modern model with superior efficiency not only for the consumer and the field of activity of where the product comes from, but also for the areas of activity in which this product is reused and then recycled. The traditional model included actions such as taking, buying, producing, acquiring, using, and throwing away. By implementing a personalized counseling functionality for a circular lifestyle, opportunities are sought and identified through which users are guided to make responsible choices and behave in a way that supports this endeavor. In the medium and long term, the process also contributes to changing the mindset and lifestyle of all users [33]. The intelligence, creativity, and inventiveness of people have no limits. We see these amazing things all around us all of the time and marvel at discoveries and ingenious solutions that break down all of the barriers of imagination. The chatbot is an AI application that communicates with users by providing helpful information and real support in any field. The developers of these IT solutions have integrated a personalized advice functionality, creating the opportunity for chatbots to take on the role of personal guides in the process of transforming consumer behavior and adopting a circular lifestyle. The chatbot's personalized advisor role involves the following five procedures:  
1. Detailed analysis of preferences and behaviors  
The chatbot collects information about user preferences, internal and external factors that lead them to uncontrollably buy products, peak consumption periods, and user behaviors over short, medium, and extended periods. Sets of questions are established with which the chatbot identifies problems, quickly collects data, and outlines personalized recommendations and advice for each discovered problem. Interactions with the chatbot are customized on the basis of the user's needs and the identified problem. On the basis of all of the data obtained, the chatbot builds a detailed profile for each user. This profile is constantly improved and modified, depending on the data that the chatbot collects about the user [34; 35]. 2. Creation of user profile  
The chatbot creates the user's personalized profile based on the collected data. This profile includes information such as consumption preferences, the amount of products purchased, periods of excess shopping, normal shopping periods, and products purchased during both of these periods, purchasing habits, their level of awareness of environmental issues, the amount of money spent on shopping to excess, what solutions are identified to promote the spending this money only for applicable purchases or for the profitable investment of this money, what solutions are recommended for adopting a circular lifestyle, and what are the short-, medium-, and long-term impacts on the user of addressing their responsibility for their lifestyle [36; 37]. 3. Personalized recommendations and continuing education  
Using advanced algorithms, the chatbot generates personalized recommendations. These may include suggestions such as the following [38]:  
* Healthy products, not chemically treated ones (food). * Products made in nearby local communities, where the consumer can go to pick/purchase, the fresh product right from the seller's household or garden. * Durable products that can be used for a longer period. * Recycling options for each product category. * Waste reduction.
