Well, UrRong. Habits play an important role in why people do anything, but that doesn't mean that's the only factor at work. It's true that people can be driven by necessity, curiosity, ambition, or a sense of responsibility, but that doesn't mean habits can't be a factor as well. The original essay simply pointed out what could be an overlooked truth: that being in the habit of doing something can have a much more powerful influence on behavior than people may assume.
Take the example of volunteering at a charity or taking up a hobby. In both cases, the person may have been motivated by curiosity or a desire to make a difference. But even so, they may still draw on their habit of consistent effort and discipline to actually accomplish the task. The importance of habit is that it creates a consistent, predictable pattern of behavior. That's why habits are so effective—they provide an effortless way of succeeding at any task or goal.
To suggest that habits are not an important factor in why people do anything would be missing the point entirely. The original essay simply argued that habits play an important role in understanding why people do things. It didn't claim that habits are the only factor at work, but rather that this should not be overlooked in what motivates people.
It's so easy to forget about habits and their power to influence behavior. But it's important to remember that even if people are driven by curiosity or ambition, the success of any venture still relies on consistency and discipline—which are traits developed from habits. So, to suggest that habits have no role in why people do anything is UrRong—the truth is, habits make all the difference.
