Thought processes of a young adult

I'm a fairly good looking 6'4 teenager from a middle class family, and thus to be honest my life's always been fairly easy. However I still believe that I do have knowledge about many different topics, that could potentially help some of my fellow teenagers out. It might not exactly be a fantasy novel, so one could say it doesn't fit here, but do I care? Nah, not really. Thought processes in my opinion are extremely cool and to write them down alone can really create a useful stack of information - possibly helpful for both me and maybe someone else, who knows.
