Trust grows when our motives are straightforward and based on mutual benefit - in other words, when we genuinely care not only for ourselves, but also for the people we interact with, lead, or serve.
Once you create trust - genuine character and competence based trust - almost everything else falls into place.
Leadership is getting results in a way that inspires trust.
It's vital to listen, to understand first. Otherwise you may be acting on assumptions that are totally incorrect - acting in ways that turn out to be embarrassing and counterproductive.
