The Principle of Equivalent trade

Full Metal Alchemist by Square Enix was nothing short of what i expected from the creators of
Final Fantasy. Intriguing plot, a meaningful theme , touching and all the comedy one might expect. The tales of two brothers, Edward and Alphonse Elric, their love for each other and most importantly, their struggle through life.
A bit of the technical aspects first. Graphics were great especially when transmuting. Music too was nothing short of a Square production.That's about it!
Actually, the only thing that really took hold of me during the whole show was it's theme, ' The Principle of Equivalent Trade'. Is it possible to believe that to gain something, you must first lose something of equal value? At first glance, it does seem like total bullocks but when given thought, it does make a little sense.
Just look at your own life. There should be many examples to it. I mean you and i, we study hard to get good results. Due to our hardwork, we achieve good results. However, the results are only part of the end bargain. It's the process of working hard which builds your character that is the real trade here. That's why, even if you felt that hard work has been toiled, think not of the result but of the process through it. This is just only an example but do you think it's right? Even when you look at a relationship, it still applies don't it? Getting married will make one forfeit one's bachelor hood. If one breaks up in a relationship, all the post suffering would be somewhat equivalent to the happiness during it. Even in the Bible, the richer one becomes on Earth, the poorer he'll be in Heaven.
Then again, it's still crap. What am i saying actually?I really don't know. Maybe it's just cause that things like that are happening to me.Hopefully it doesn't apply for my exam though. Neither the time or will to go through it.Christmas spirit!Joy to the world,the Lord has come, may He blabalbla!
I've nothing much else to say...Guess that's it!
