我好奇故我在

There is no objective reality. There are no facts. There are no best products. All that exists in the world of marketing are the perceptions in the minds of the consumers or prospects. The perception is the reality. Everything else is an illusion. Period.

我蠻喜歡這段話的：沒有所謂的客觀事實，沒有所謂的實情，沒有所謂的最好產品。所有行銷世界都是存在消費者或潛在消費者的腦中的認知。他們的認知才是事實，其他的都是幻覺！(Perid翻成句號，在英文中是很強烈的表示意見結束了，沒有別的)
