A leader’s role is temporary but the organization lasts for decades. A successful leader creates an environment and trains and motivates their team so that teaching and learning continue even in their absence.
You don’t want to be a control-free leader but create an environment where teaching philosophy has deeply ingrained within your organization. Whether you stay or not, present or absent, the organization performs to its core.
If you want the organisation to function on its own carrying your teachings and philosophy then you have to ingrain it within.
