Signature strengths are the strengths that a person possesses and that are most characteristic of their personality and behavior. These are the strengths that the person frequently uses naturally and intuitively, and that bring them the greatest satisfaction and meaning in their life and work.

Signature strengths are a central part of the strengths-based approach to personal development, and they can be identified using a variety of methods, including surveys, interviews, and observations.

According to research conducted by Marcus Buckingham and Donald O. Clifton, there are 34 strengths that are common to all people and form the foundation of signature strengths. These 34 strengths include, for example, goal orientation, flexibility, analytical thinking, communication, fairness, strategic thinking, and harmony.

When a person knows their signature strengths, they can use them to improve their performance, well-being, and success in life and at work. They can also leverage their signature strengths to create more meaningful relationships and contribute to their community in a way that aligns with their personal values and beliefs.
