on giving up

giving up is usually seen as a sign of weakness. for most people, it's something terrible: one shall always do whatever one can in order to succeed, regardless of the cost. if you ask me, to give up is not something shameful. well, sometimes it is, but not all the time, not even in most of time. a sign of weakness? there is no weakness in surrendering to a clearly superior foe, only common sense. as there is no weakness in acknowledging our limitations. the age of heroes is long gone, and not all the battles are meant to be won. besides, sometimes victory comes at a cost that we cannot simply afford. and sometimes the tides change, and what we believed we wanted, we want no more. is it worth keep struggling for something we no longer desire?
