Knowledge is Power. Ignorance is Bliss.
Focus on what is important in your life at all time. Do not need to bother about others' mind and thoughts onto you as it is really none of our business as we can only control our emotions and mindset.
Why do we need to care about others' idiotic, self-centred and narrow minded individuals. Focus on own happiness and what make you happy is more important than how to make other's happy.
Have inner happiness and peace is most important one self should have.
