I have to know everything.
If you have to know everything, you are telling people they have not earned your trust.
It is natural to desire respect and trust. Every leader needs to know that he/she is respected and trusted. To be respected and trusted, you must respect the individual and trust her/him to apply her/his unique strengths.
Earning respect and trust is a commitment and takes time. You must spend time skillfully learning about the individuals diverse knowledge, skills, and abilities. You do this to know how to best lead them in applying their authenticity – just like you are modeling for them.
You have now learned how to ‘delegate for development’ … and this is how you support your focus – resulting in mutual respect and trust.
