Valter Alcoforado Barreira discusses the importance of social capital and how professional affiliations can help build social capital. Social capital refers to the support and resources available through social networks. Professional groups provide opportunities to develop both weak bonds with acquaintances to gain new information, and strong bonds with strategic contacts through shared activities and goals. Groups like the Portuguese-German Chamber of Commerce Young Entrepreneurs and Professionals allow members to expand their networks and access new opportunities outside their normal social circles. Barreira encourages reflecting on the benefits of involvement in professional groups to increase social capital.
