More general: "you should have an environment that is conductive to you doing X". Lots of people thrive in adversity, and a notable minority aren't very social. This may actually be true for most people in limited situations... I was very unlikely to clean up other people's liter and dog poop until I moved into a neighborhood where 1) no one cleans up at all and 2) people thought it was weird to do so. (If instead they had thought that they should clean up, but were too lazy, I would have seen the mess as a fitting punishment for their laziness, and would only have cleaned up that which directly impinged on my immediate environment). Of course, I don't give this as an example of a healthy environment, just as an example where a motivation to do productive work is not dependent on social support.
