Decades ago and when I was very concerned to build my own logic, my first and most important goal was to analyse as deep as possible the structure I was made of. It was much like the way that one likes to explore all the rules and features of an IC or a system he wants to work with.

In brief, I discovered that I was made (not necessarily true for all creatures) mainly by two distinct beings though fully correlated.
The first is a being formed by all related components (atoms, cells and organs) that are defined, to exist as I am, by a huge set of rules but all are confined to our actual time/space notion.
The second is a being in me that I also perceive or feel though it is defined by another set of rules that have nothing to do with the time/space limitation.

On the other hand and I like it or not, I found also that I was rather programmed to learn what is the best state I like to be and to find the best way or path to reach that state as close as possible.

Hence in my case, I had two beings in me to take care of.
For example, studying electronics (with all the necessary background) gave my first being the joy in creating new practical methods and sets while gaining its daily bread too. I am saying that though I am sure that the world, with or without me personally, will not change and it doesn't really need, in the first place, my existence and/or my work. In fact, many others would fill, in a way or another, the gap of my absence.

That is all I can add because it is not logical for me to go on more than that here.
This forum is about 8052 studies that formed a great and interesting part in my life (of my first being of course :D ).
