Good points, but some of what I plan (long-term) is dependent on what is in the first book. I have to make sure it is right, or what I want (if things work out) will be problematic.
I'm doing 3-4, 3-hour work sessions a day on my project. No procrastination here. I am doing many things. For example, I recently finished new databases that will help me recall all the learning I did from numerous sources. I have command centers to use Ctrl+F to find what I need, when I need it (if I forget).
Learning how to write a novel, then learning how to write a novel series, is very complicated. There is a huge learning curve. I learned a lot in a relatively short amount of time, and it is impossible to retain it all. I had to take the time to build these command centers of knowledge, so I do not take the time trying to find the resources I once learned for the details I need to get through a technical hiccup (and slow my creative flow). This may be procrastination to one, but not to me. I will use these documents for every book, short story, character I develop, world I build, and so forth. The time invested, for me, to build these databases was well worth it.
Thank you for the insight. I appreciate what you are saying, but, for me, there are other considerations I must contend with, or my chances to succeed will diminish. This is my opinion of course.
