"Create a detailed black-and-white illustration for Chapter 1 of the book 'Vertriebskunst: Der geheime Code des Verkaufserfolgs.' The illustration should clearly convey the following elements: Definition and Importance of Sales: Depict a business setting with a professional salesperson and a client shaking hands, symbolizing the transaction and the value exchange. Highlight the importance of building relationships and trust in sales. Key Characteristics of a Successful Salesperson: Show a successful salesperson with visual attributes such as confidence, good communication skills, empathy, and perseverance. Include icons or subtle symbols representing these qualities, like a speech bubble for communication, a heart for empathy, and a trophy for success. First Steps in the Sales Process: Illustrate the initial stages of the sales process. This can include research and preparation, an initial meeting, and the beginning of relationship-building. Show the salesperson making notes, meeting a client for the first time, and establishing a connection. The overall design should be clear and organized, with each section distinctly represented yet harmoniously integrated into a single cohesive image. The black-and-white palette should enhance the clarity and focus of the illustration, ensuring it is visually appealing and easy to understand."
