My Hands Lock and Morality

Once my superstitious school teacher of history said in class that your hands indicate what part of brain is dominating - the way you put them in the lock (finger after finger from one hand then another, you know that 'pose'). So, just for fun without really thinking about the consequences I decided to change the way I put my hands in lock. Now my thumb of the left hand is on the top though before the right one was.
I am not sure that what my teacher said was right (I actually doubt it, never heard of scientifically proven facts on the matter) but after that somewhere inside I realized that a man can change anything in himself - from such small things, that seemed natural for him from the time he learned how to lock his hands, to much bigger things (i.e. the brain, if the theory of the teacher was right).
It's just one of the lessons I learned.
And sometimes the thought comes to my mind: I want to change my life. Well, I definitely have everything I need for that - I have myself and my willpower.
And yet another thing I understood lately (mostly after I read my bro's paper) that I'm young and inexperienced in many things and I'm still getting used to myself. So, what I am doing now is making acquaintance with myself, knowing my powers and my weak sides. And I'm setting those things myself: I give me goals/tasks/todos and wait for the results. What I'm trying to say is you can only know yourself through doing things, not sitting and thinking about life (that was taken from Goethe) and more than that you have an ultimate responsibility before yourself. When you upset yourself with the outcome, your self-esteem goes down, you won't believe in your strength, you will set easier tasks because you won't expect much of yourself anymore. Thinking about that stuff is slightly mingboggling.
And recently (after I spoke with granny and parents about my bf - for quite a long time) I've started to pay attention to the development of the society. How much things changed since my parents were like me. I was born in the world after the sexual revolution, after the 1990-s events in Russia, after the Internet was introduced. I was growing up in the world of freedom in everything - thoughts, mass media, information, relationships, government actions etc. I am really surprised how I become who I am with all these prejudices over smoking, drinking, making out in public... I guess my parents gave me that through upbringing. But still my morality differs from theirs. Some things seem sound to me, reasonable and normal while they think of them as unacceptable and vice versa. Maybe it's only me against the whole world thinking the other way (oh, noes) but I like to shift it on the society (with Eddie Vedder on my mind). Indeed, I feel a little bit like its crazy breed.
