The aim of the "Let's Talk About Money: Financial Sustainability" project was to develop young people's practical financial skills through activities and exchanges with participants from six economically diverse countries: Cyprus, Finland, Germany, Hungary, Poland, and Serbia. Participants not only gained knowledge but, above all, learned to apply it in practice. One of the main goals was to develop their own beliefs about money and understand financial mechanisms. This was achieved through simulation games and tasks in urban spaces (e.g., interactions with Lublin residents), which exposed participants to real differences in access to resources and approaches to managing household budgets and saving. Another goal was to develop personal finance management skills. Participants worked on specific examples: they created their own budgets, analyzed income and expenses, compared living costs, and learned about various forms of investing and saving. At the same time, they developed negotiation skills (sales and pricing simulations) and analyzed the components of product prices. The project also involved learning about finance in practice – both in the private and public sectors. Visits to Unitrailer and Lublin City Hall allowed participants to see strategic planning, marketing, and financial decision-making in real-world organizations. Developing entrepreneurship and creativity was also a key goal. Participants worked on marketing case studies, created promotional strategies, and solved simulated financial problems (e.g., managing a theater and selecting profitable activities). This allowed them to learn decision-making under limited resources. The project also aimed to prepare participants to share their knowledge. The youth designed and conducted financial education workshops for children and young people, allowing them to consolidate their acquired knowledge and develop leadership and educational skills. Another important goal was to increase social awareness and responsibility in the area of finance. Participants explored topics such as employee rights, assertiveness at work, business ethics, and greenwashing. The project also addressed the topic of financial stability in the cultural sector during meetings with practitioners from the Academy of Modern Art and the Eastern Theatre. Additionally, the project supported the development of intercultural competences through international teamwork, national evenings, and methods such as the Living Library. Participants learned to communicate, collaborate, and exchange perspectives on money, work, and lifestyle. The final goal was to strengthen participants' agency and encourage them to take further action. The project concluded with reflection, evaluation, and the preparation of dissemination materials (e.g., infographics), which allowed participants to organize their knowledge and plan its future use.
