Strengths are built-in capacities for certain thoughts, feelings, and behaviors. Everyone has these capacities to one degree or another. Your particular pattern of strengths is part of what makes you unique.
When you play from your strengths, you are likely to feel more energetic and perform better than when you are trying to use a capacity that comes less naturally. For example, one person trying to influence a local school board to ban soft drink sales might have the strength to speak up forcefully and clearly at a general meeting (despite the almost-universal fear of public speaking). Another person strong in team-building might feel uncomfortable speaking out in a meeting but could successfully build consensus among parents, nutritionists, and others to weigh the issue and come to a decision.
Leveraging your strengths can help you accomplish many goals. Making your strengths work for you, especially when the task at hand is well-aligned with your personal values, can leave you feeling more competent and connected.
