I'm an old man who seeks a guarantee of enough time left for me to finish this tome if once I begin the arduous endeavor that is necessary for the journey. I have started, but disengaged to ask for guidance, and more importantly the real possibility of an old man, I'm getting older by second, finishing this book. By the way, I read slowly. So, I need an answer quickly, no dilly dally, should I continue? Yes of NO.
