Positive psychology, studying it, applying the ideas to my life has made me significantly happier. It continues to make me happier. And it was when I realized the impact that it had on me that I decided to share it with others. That's when I decided that I want to be a teacher and teach this field. So this is positive psychology, psychology 1504. And we will be exploring this new, relatively new and fascinating field and hopefully we will be exploring more than the field, ourselves. When I first taught this class was back in 2002, I taught it at a seminar and had eight students. Two dropped out, that left me with six. The year after, the class became slightly larger, I had over 300 students. And then the third year when I taught it, which was the last time, I had 850 students in the class making it at that point the largest course at Harvard. And that's when the media became interested.
研究積極心理學(xué)并將其應(yīng)用到我的生活中，這明顯使我變得更幸福了。并且讓我繼續(xù)幸福下去。當(dāng)我意識到這些發(fā)生在我自己身上的影響時(shí)，我決定將它與別人分享。于是我決定要成為一名教師并且教授這個(gè)領(lǐng)域。這就是積極心理學(xué)，心理學(xué)1504課程。我們將探索這個(gè)相對新興并且引人入勝的領(lǐng)域，希望我們能從中悟出領(lǐng)域之外的東西—我們自己。我第一次教這門課還是在2002年，我當(dāng)時(shí)教的是研討班，只有8個(gè)學(xué)生。還有2個(gè)人中途退出，只剩下6個(gè)學(xué)生。1年后，班級規(guī)模稍微大了點(diǎn)，我有了300多個(gè)學(xué)生。然后就是第3年，也是我最后一次授課，我有了850名學(xué)生，以至于它成了當(dāng)時(shí)哈佛最大的一門課。于是媒體也感興趣了。
