Great question! Yes, people feel a lack of confidence for many reasons - there really is no "one size fits all" solution for building confidence.
However, this course starts by setting a foundation for building confidence. The first two modules focus on understanding confidence and doing a self-assessment of where you're at - and the third module gives you specific tools for working through common leadership situations, such as handling difficult conversations, for example.
The exercises are designed for you to apply the course material to your role and workplace - carrying out the exercises will raise your self-awareness and help you take action in your specific situation.
