Our robot would never do activities that are extrinsically pleasurable.

机器人绝对不会去做外源性愉快的活动。

Activities that are extrinsically pleasurable are harder to focus on because the activity itself is not pleasurable.

外源性愉快的活动更难专注，因为这些活动本身并不令人愉快。

So if you can find a way, either intrinsically or extrinsically, to get more interested in a single task that you want to do.

所以说，无论是发自内心的还是外在的，去发现，你需要做的事情里更多的乐趣。

So I desire to engage in exercise and I value exercise extrinsically...not for its own sake, but as a means to something beyond it. It brings me good health.

所以我愿意加入锻炼是因为我重视锻炼的外在价值，而不是锻炼本身，是把它作为达成另一目的一种方式。它给我带来好身体。
