However, if Michael Jordan hadn't worked on his basketball, I would be a better player than he is.
但是，如果迈克尔·乔丹从没练过篮球我应该能比他打的好
If he didn't work on his basketball at all, and I did and do.
如果他从没练过的话，而且我的确练过
In other words also with genes, people who don't work on their happiness
换句话说，在遗传作用的前提下，不去努力争取幸福的人
even if they have the best of genes will not do as well as people with less happy genes who work on it.
即便他们有最好的遗传基因，也不会比基因不如他们但努力争取的人快乐
So work matters a great deal.
所以说，后天努力至关重要
The second thing that matters that makes up the hundred percent of variance of happiness, external circumstances.
第二个对快乐差异指数有影响的因素是外部环境
Of course, extreme circumstances make a lot of difference, whether we're living in a free country versus oppression. That makes a lot of difference.
当然了，外部环境很重要，我们生活在一个自由的国度，还是受人压迫，带来的结果是完全不同的

However, in general, external circumstances beyond the extremes, beyond being homeless on the street, make very little difference,
但总的来说，外部环境只要不过于极端，比如无家可归流浪街头，其实影响不大
in fact, about 10% of the total variance.
在差异方面只有10%的作用
So genetic genes 50%, external circumstances such as place of residence, such as income, such as weather.
因此遗传作用50%，外部环境包括居住地，包括收入，天气等等
And again not for people, for example, who have seasonal affective disorder.
另外这个不包括，有季节性情感异常的患者
Then of course it matters whether we get sun or not.
对于他们来说，有没有阳光太重要了
I'm talking about, um, most people, not people with SAD.
我现在说的是大部分人，不包括有季节性情感异常的人
So out of these extremes, external circumstances make, matter about 10%, not much.
因此除去极端案例，外部环境的作用不大，大概是10%
The third thing, the rest of the 40% is accounted for by intentional activities.
第三点，剩下的40%是由意向活动决定
