It is no crime to be ignorant of economics, which is, after all, a specialized discipline and one that most people consider to be a 'dismal science.' But it is totally irresponsible to have a loud and vociferous opinion on economic subjects while remaining in this state of ignorance.
Be aware of yourself and know yourself. No matter how much you have learned and how much you know, if you don't know yourself you don't know anything. Indeed, if you don't know yourself you cannot know anything else. People who don't know themselves criticize others from the point of view of their own ignorance. They consider what agrees with them to be good, and hate whatever doesn't go their way. They become irritated about everything, causing themselves to suffer by themselves, bothering themselves solely because of their own prejudices. If you know that not everyone will be agreeable to you, know that you won't be agreeable to everyone either. Those who have no prejudices in themselves do not reject people, and therefore people do not reject them.
Meditation brings wisdom; lack of mediation leaves ignorance. Know well what leads you forward and what hold you back, and choose the path that leads to wisdom.
I took a closer look. There is no such thing as ignorance. Ignorance is nothing But my limited knowledge. I took a closer look. There is no such thing as defeat. Defeat is nothing But the inspirer Of my increasing will. I took a closer look. There is no such thing as death. Death is nothing But my strengthening And Dreaming rest.
Each human being can at once be a fighter and forgiver. When self-doubt tortures him, he most play the role of a fighter. And when his own ignorance humiliates him, he must play the role of a forgiver.

It is in the admission of ignorance and the admission of uncertainty that there is a hope for the continuous motion of human beings in some direction that doesn't get confined, permanently blocked, as it has so many times before various periods in the history of man.
