Much of what we do each day is automatic and guided by habit, requiring little conscious awareness, and that’s not a bad thing. As Duhigg explains, our habits are necessary mental energy savers. ①We need to relieve our conscious minds so we can solve new problems as they come up. ② Once we’ve solved the puzzle of how to ballroom dance, for example, we can do it by habit, and so be mentally freed to focus on a conversation while dancing instead. ③ But try to talk when first learning to dance the tango, and it’s a disaster ― we need our conscious attention to focus on the steps. ④ Tango musicians bring different genres of music together to attract a more diverse audience from varying backgrounds. ⑤ Imagine how little we’d accomplish if we had to focus consciously on every behavior ― e.g., on where to place our feet for each step we take.
