Power within is related to a person’s “sense of self-worth and self-knowledge; it includes an ability to recognize individual differences while respecting others” [1] (p. 45). Power within involves people having a sense of their own capacity and self-worth [2]. Power within allows people to recognise their “power to” and “power with”, and believe they can make a difference [1].
I've seen definitions of the others before but not "power within".
