Wallace's hack is particularly cool because it uses the prefrontal cortex (over which you have at least some level of conscious control) to create stories that trick your limbic brain into generating the preferred emotional response.
I've seen this referred to as "riding an elephant", because the "rider" (the conscious mind) can skillfully manipulate the "elephant" (the bulk of the brain), but ultimately remains at the larger creature's mercy. Great image.
I actually read to do this in some silly self-help book (Don't Sweat The Small Stuff, perhaps?) years ago. It's helped a lot.
Really, we've all been there. In an absolute hurry. I don't necessarily imagine them in a scenario where the hurried pace is necessary; I just know that in the moment things feel far more urgent than they need to.
I think it's been answered pretty well by other people here w.r.t. the mixed reputation of self-help books, with a side of embarrassment for admitting I read one (which is really nothing to be embarrassed about).
Some of them lack science. Worse, some of them are actively anti-science.
I agree that there some great books, with useful helpful life-changing advice.
Highly recommended listening.
everything in my own immediate experience supports my deep belief that I am the absolute centre of the universe, the realest, most vivid and important person in existence. We rarely talk about this sort of natural, basic self-centredness, because it's so socially repulsive.... Other people's thoughts and feelings have to be communicated to you somehow, but your own are so immediate, urgent, real....
The remedy he proposed:
[Instead:] if you're aware enough to give yourself a choice, you can choose to look differently at this fat, dead-eyed, over-made-up lady who just screamed at her little child in the checkout line - maybe she's not usually like this; maybe she's been up three straight nights holding the hand of her husband who's dying of bone cancer, or maybe this very lady is the low-wage clerk at the Motor Vehicles Dept who just yesterday helped your spouse resolve a nightmarish red-tape problem through some small act of bureaucratic kindness. Of course, none of this is likely, but it's also not impossible - it just depends on what you want to consider.

What works for me sometimes in dealing with customer-service folk is to ask them what they would do in my position.
