To learn knowledge

Ignorance leads to fear,

fear leads to hate,

and hate leads to violence.

This is the equation.

—Rabbi Tzvi Freeman

There are too many noise in the real world,and when people are in it,they absorb those noises and turn to either unconsciousness or confusion.That's becasue of the wrong information they got,which I meant by noise.

So first of first,the most important thing is to ascertain right thing from wrong.But how to do this?it's still a very huge problem.Well,everybody need to humble oneself,for me,I admit there's a true God actually.

Second,Logic is a great tool to help to tell right different from wrong.if you know logic,you could avoid most traps in the world.

And then,the most important thing comes up.that is,we need to learn real knowledge,not just the knowledge to make money but the knowledge to fix things right.which is rare and really important.Back to the very beginning,Rabbi Tzvi Freeman is right,we just need those knowledge to conquer ignorance.

Every heart is empty,greed grows fast and rightousness grows slow.this is the real world.

Like the saying in Chinese Buddism:Knowledge likes lamp,lamp can light the dark.and stupidity is dark.愚如黑暗，智慧如灯，灯能照暗。
