The document discusses synergy and how building synergy between groups can provide benefits when facing problems or difficulties. Synergy is defined as the interaction between two or more agents that results in an effect greater than the sum of their individual effects. Applying synergy concepts to areas like family, business, and friends allows a group to focus their combined energy to quickly solve problems while sharing activities and stress. This results in feelings of comfort during losses, complete integration, job satisfaction, and trust within the group. The document recommends ways to build synergy such as acting as a whole, building trust, encouraging flexibility, leading by example, and being polite. When synergy is applied, it can help people overcome obstacles and view problems as challenges.
