Even if you do things the right way, some people would still be not satisfied. Others will not appreciate what you say and what you do. There will always be people who would let you down.
But, as long as you speak from your heart, you speak with virtue and with integrity you will be fine.
This is not a perfect world. This is not a perfect life.
Life is almost always unfair and
WE are not born to please the whole world.
