Here are our initial objectives: - To offer activities that foster the development of resilience in every young person. - To provide pleasure through activity, effort and challenge. - Encourage exchanges in foreign languages (English, French for the Italians). - Generate a permanent "positive attitude" to overcome the difficulties of the proposed activities (during the mobility), and everyday life (after the activities). - Giving/restoring a taste for daydreaming, intellectualisation, abstraction and humour. And sport seems to represent a very interesting lever, as it combines the values that are essential for overcoming difficulties: a sense of effort, solidarity, perseverance, a taste for challenge, a sense of purpose.
