In the 19th century, there used to be a model of how to be a good person. There are all these torrents of passion flowing through you. Your job, as captain of your soul, is to erect dams to keep these passions in check. Your job is to just say no to laziness, lust, greed, drug use and the other sins.

  These days that model is out of fashion. You usually can’t change your behavior by simply resolving to do something. Knowing what to do is not the same as being able to do it. Your willpower is not like a dam that can block the torrent of self-indulgence. It's more like a muscle, which tires easily. Moreover, you're a social being. If everybody around you is overeating, you’ll probably do so, too.

  The 19th-century character model was based on an understanding of free will. Today, we know that free will is bounded. People can change their lives, but ordering change is not simple because many things, even within ourselves, are beyond our direct control.

  Much of our behavior, for example, is guided by unconscious habits. Researchers at Duke University calculated that more than 40 percent of the actions we take are governed by habit, not actual decisions. Researchers have also come to understand the structure of habits—cue, routine, reward.

  You can change your own personal habits. If you leave running shorts on the floor at night, that'll be a cue to go running in the morning. Don’t try to ignore your afternoon snack craving. Every time you feel the cue for a snack, insert another routine. Take a walk.

  Their research thus implies a different character model, which is supposed to manipulate the neuralnetworks inside.

  To be an effective person, under this model, you are supposed to coolly examine your own unconscious habits, and the habits of those under your care. You are supposed to devise strategies to alter the cues and routines. Every relationship becomes slightly manipulative, including your relationship with yourself. You're trying to arouse certain responses by implanting certain cues.

  This is a bit disturbing, because the important habitual neural networks are not formed by mere routine, nor can they be reversed by clever cues. They are burned in by emotion and strengthened by strong yearnings, like the yearnings for admiration and righteousness.

  If you think you can change your life in a clever way, the way an advertiser can get you to buy an air freshener, you’re probably wrong. As the Victorians understood, if you want to change your life, don’t just look for a clever cue. Commit to some larger global belief.
