Your response was very helpful, thank you Jason! I would be remiss not to mention how much your book has helped me with the " the evaluation of business models, their prospects, and their management; and then in modeling the future performance of the business." I learned how to model (I speak specifically about the mechanics of a DCF model) well before I learned how to make a determination about 1) what I thought to be the most relevant factors and 2) how to understand and clarify what most likely would unfold in the future for the most relevant factors.
