Which of the following is NOT one of the three criteria for a signature character strength?

The reasoning behind identifying that the motivation to use a strength should come from within rather than from external influences, such as colleagues, is vital in understanding what defines a signature character strength. Signature strengths are intrinsic qualities that resonate deeply with an individual’s sense of identity and purpose. When someone feels energized by using a strength and feels that it reflects their true self—which are key indicators of a signature strength—they are more likely to experience a sense of fulfillment and satisfaction in their actions.

In contrast, relying on external motivation detracts from the personal nature of what makes a strength "signature." If motivation is sourced from colleagues or other external factors, it shifts the focus from genuine personal alignment to fulfilling others' expectations or needs. Signature character strengths should be rooted in personal conviction, leading to authentic engagement and satisfaction. Hence, the criterion pointing to motivation derived from colleagues does not align with the essence of what constitutes a signature character strength.
