When it comes to “comfortable,” it is useful to consider the economist Tibor Scitovsky, who argued in his book The Joyless Economy that there are two kinds of positive experiences—pleasures and comforts—and that we have a tendency to take the comfortable, safe, and predictable path way too often. This is particularly sad, Scitovsky argues, because real progress—as well as real pleasure—comes from taking risks and trying very different approaches to life and types of experiences.
