Introduction. When I wrote down that word in the title, already looking for ideas to fill in the blog entry, I was wondering: have we been introduced? Do you know me, you who read me, speak about me or talk to me? Maybe, maybe not. Texts published here may denote that I have the easy life, having fun, traveling around the world. But, as an example, how many have any idea about what happened in my life over the last year and a half.
