Leaders in a culture of change

I has been a striking point to me personally that there is a clear distinction between leaders and managers
In the Fullan text on page 2 it clearly states that leadership is needed for problems that do not have easy answers.
This has got me thinking that leaders are not just good managers - they have a unique responsibility to mae sure people are aware of problems and the need to change and also to address them in a way that will bring about the best possible response from employees as possible.
Leaders are managers but also much more. They are not just managers.
On pafge 3 of theu Fullan text it states that lepasership is not mobilising others to solve problems we already know how to solve, but helping them to confront problems that have not yet been addressed successfully.

This has led to a personal relevation that if I am to be a good leader I need to be aware that I am to lead others not just to solve problems they can see and know how to answer but to direct their awareness to see andj understand that there may be problems either currently existing or coming up in the future to whcih there are no solutions yet available and upon which we all much collaboratively act.
I am not just to be a good manager but also a good insightful proactive foreseer of future problems and of problems that yet have no answers.
