New approaches will and have to be created.

Conclusion

You cannot really be a good manager and not being willing to learn new things. It is of great importance to think about about your development. You can learn just about everything, thanks to a very wide range of management development programs and the web. The way you do is relevant as well. The classical lectures and courses methods are not as effective as they should be. A much better solution is to take part in a program that allows you to directly put your knowledge into practice. Most important of all: Accept personal responsibility for your own growth; no one can do it for you. Not only in management.
