That's the thing. I didn't voice any doubt at all about my big plan.
Perhaps I misinterpreted him, but it seemed to me he was addressing all of it - the plan, the book, the trimmings.
If I did expand his point inappropriately, I apologize.
Is your past 'performance' indicative of future 'performance' in any way?
Maybe I'll clarify myself as well. When addressing the original poster, and stating that I appreciate the subject, it would be wildly inappropriate to predict my future in order to convince him, no matter how certain I am of it. I can ONLY speak to what has happened already.
My own inner narrative is my own, and I can predict as I wish.
If you want an honest answer to your question, in the vast majority of situations past performance is extremely indicative of future performance. To state otherwise would be silly.
However, I have my big plan, so "not in this case".
