Generally, in this first phase, you spend a lot of time learning about great people. You pick up books about inspirational men and women, you pay attention to those admirable people around you and you start mimicking the qualities in them that you admire. I can remember in seminary watching many of my classmates mirroring our homiletics (fancy word for the guy that taught us how to preach) professor. The interesting thing is that the students did not even know that they were doing this. Over time, his voice became their voice. His emphasis because their emphasis and so on. There is nothing wrong with this, and is very appropriate during this stage. Great men and women are admired and worthy of our modeling.
Stage Two: Looking IN
Stage Three: Moving ON
This is the point in your life where you develop your own voice.
You are your own person. You express yourself in your own way. People know your style and more than this, people can identify it as yours alone. People stand back and say, "Anthony just preached a sermon that only Anthony can preach."
Unfortunately, for many people, their development stalls in the 1st stage. The reason?
It is easy to remain there. Don't kid yourself. In order to get to the 3rd stage, it will take all of your resources. And when I mean all. I mean ALL. Time, energy, money, family, friends, Etc.
