Head Coach Evolution

I'm curious what my fellow head coaches feel about how much our beliefs, philosophies, and just general way of doing things change during the course of our career. And how fast? I am entering my sixth year of being a head coach, all at the same school, my 14th year in coaching FB. But I feel I'm just now starting to develop what I consider my own way of doing things, what I like and don't like, what I think works and what I don't. Is this a normal progression for head coaches? I thought I knew what I wanted to do, I had a plan, I had a philosophy, but was it really mine or just the one I adopted from the coach I worked (and played) for prior to becoming a head coach? Obviously, there are many parts of my philosophy (or barrowed philosophy) that haven't changed. The importance of the weight program, fundamentals, persistance, out-preparing your opponent, why we coach, things like that. But things I've come to believe in that are very different from what I started out believing. Example: Option Offense; I can't imagine going to another school and not running an option offense. But I'm a self taught option coach, and it's not what I set out to run. My offensive philosophy has evolved, mostly out of neccesity, because of where and the kind of kids I coach. Has anyone had a similar experience? If I go somewhere else, will my philosophy once again evolve? How much should it change?
