Just because you have domain knowledge does not give you permission to lecture, puff and demand people to listen.
Teach, coach and guide others with your expertise and experience. Don't use it as a bargaining chip for power, status or safety.
Encourage others to grow in their own knowledge. Share wisdom widely by not holding it close to your chest in protection. It is not even yours to protect.
Challenge, provoke to action and champion others with your experience but seldom as leverage for self-esteem, power or manipulation.
