Situational Leadership

For class, I have decided to read The 7 Habits of Highly Effective People by Stephen Covey. I feel that this book will help develop my leadership skills. Most people that I have spoken to that have read this book all have positive things to say.
In class on Monday, Adrian Klemme came to speak to us about situational leadership. He tried to convey to each of us that a leader must act in a flexible manner depending on the situation. To help us do this, he showed us a situational leadership model. In this model, there were four different sections, which are:
1- Directing: This style is meant for those that are inexperienced. You must be able to guide and 'direct'.
2- Coaching: This is a style that focuses more on teaching.
3- Supporting: In this style, you are meant to back up the individual(s) you are leading. They don't need to be guided, but rather supported.
4- Delegating: This is a style where you distribute responsibility. You can rely on those working with you because they are able to perform at high levels. Because of this, it can be a very effective form of leadership.
After this lecture, I was wondering how I could apply these four steps into my leadership role and ability. I realized that this applies to anyone I associate with. Also, that there isn't one perfect style of leadership. Also, I realized that my style should flow between all four of these sections.
