Questions about the insignificance of one's actions.

The unbearable lightness of being...OR IS IT REALLY SO LITE??that would be one thing I can accept after a drunken stupor in the wee hours of morning ..something when I am wasted and not normal...anywayz not in my rite senses.. To ppl who say decisions dont bind, I just ask --are they so light so as to belittle its significance in the longer run...IS ONCE REALLY NONCE?? Then the decision maker in question is just as insignificant and unworthy of existing as the decision itself...
