this "brainwashing" method doesnt always work because you are
trying to force and replace what you already experienced with a
different perspective, it does not address the root
why not try to observe that your "feelings" are impermanent, they
come and they will go, their true nature is emptiness, and think
about all those times that you acted on these impermanent feelings,
how you unconsciously let your heart project itself onto your
external environment, how your own heart toyed with your thoughts
and actions
how silly and unwise that you were unable to see through the
fascade
and if you practise this enough, you will start to relish every
time you meet these "assholes" because they provide you another
good opportunity to tame your own heart, and only when your own
heart is tamed and still, these "assholes" will cease to
exist
