it's the only one i have

given that we have only one life to control in totality, given that death is certain, assuming for convenience that the length of our lifetime is predetermined, it seems we are left with two choices really. either we spend our lifetime in laughter and happiness, or we spend it in misery and stress. if, at every discernible unit of time, we are faced with two isolated possibilities, is it rocket science to figure out which path we should end up taking?!

yes, this is an oversimplification. we rarely find ourselves in such clear-cut situations, you'd think. the truth is though, we need to force that choice upon ourselves, in more cases than not. it's all about getting accustomed after all. first, forcing the habit. then, natural ease.
