You need to do your own Thinking. Dont get caught up in mass hysteria. - Jack Scwager

Quote

Independence: You need to do your own thinking
Don’t get caught up in mass hysteria.
By the time a story is making the cover
of the national periodicals, the trend is probably
near the end. . . . Never listen to the
opinions of others.
