Team building can help build on happiness, as it provides an outlet for both informal conversation and problem-solving skills in a fun way. Getting everyone working together brings out attributes in character and helps to develop confidence in an informal environment. This increased self-worth and ability to feel better about yourself in different situations can help to build the way you communicate and interact with others.
Opening yourself to new connections can create different interactions and experiences with new people. Team building in an informal setting helps to bring these new connections together.
