Thanks everyone for the kind and helpful replies.

Before the joy of writing, my initial hobby is to research interesting subjects, such as writing memoir/nonfiction etc, and to learn as much as I can about them.

It is the love for knowledge, and to learn many aspects of things.

I also like to find "peals of wisdom" in any book that I read, and sometimes, there are subjects that are covered over and over again, while others are more difficult to find.

So, when I am asking for guidance, it is only after many hours of reading, yet not finding enough relevant info.

Also, my quest to understand things evolves all the time, and in order to complete the puzzle, I need to cross-reference information, from different disciplines.

Thanks you all for the kind advice.
