Everyone has them. Everyone seeks them.
It seems as though that one can only attain one's hopes by working relentlessly towards it. Undeniably, this is true. Cause-and-effect. Effort must be invested before the fruits of success can be seen.
At some point, ironically, the converse is true too. Only by deciding to walk away and give up, can one achieve one's goals.
At some point, the only leverage that one has is the power to walk away. It's like bargaining for a Turkish carpet - the lesser one wants it, the more likely he'll get it. (Particularly true w.r.t. unquantifiable human relations.)
