Throw away all ideals.
Stop listening to people who claim to know.
No one knows.
Name someone who knows.
Same name belongs to ignorance.
Make your own observations.
Draw your own conclusions.
There is no right or wrong.
There is only you and reality you observe.
Some cling onto thoughts that do not match reality. Instead of trying to fit ideas to observations, they make selective observations and interpret them in convoluted and far-fetched ways to fit their ideas. Such individuals are despicable and untrustworthy. But do not insult them as it will only make them yet more irrational. Ignore them and be on your way. Try to correct them if you must, but don't waste all your life on them. They should live their lives as they will. And so should you.
The world is not black and white. Not even a spectrum of colors will fit reality of a grain of sand. Do not attempt to simplify reality for the sake of your ideas. Change your ideas so that they may better fit your observations. There is no right and wrong. There is only degree of consistency with reality.
