Remember the previous comment about seldom developing a model in the form it needs to be on the first try? Investigation of a simple “Rabbit Population” model should be most informative.

As demonstrated in the unfolding of this model, you should approach the development of a model as a learning experience. When things go wrong it’s an opportunity for learning. You learn from the model and the model learns from you. Once the two of you learn enough it’s probably a meaningful model.
