I'd nominate C.S. Lewis's The Screwtape Letters as a soft skills book, that gives your System 1 a lot of vivid, specific ways human thinking goes wrong to chew on and find ways out of.

One of my favorite examples is this passage which made a big impression on my System 1 about things that do bore me but I nonetheless get sucked into. (Context note: Screwtape Letters is written as a series of letters from a senior devil to a junior tempter about how to lead human lives astray)

You will find that anything or nothing is sufficient to attract his wandering attention. You no longer need a good book, which he really likes, to keep him from his prayers or his work or his sleep; a column of advertisements in yesterday's paper will do. You can make him waste his time not only in conversation he enjoys with people whom he likes, but also in conversations with those he cares nothing about, on subjects that bore him. You can make him do nothing at all for long periods. You can keep him up late at night, not roistering, but staring at a dead fire in a cold room. All the healthy and outgoing activities which we want him to avoid can be inhibited and nothing given in return, so that at last he may say...'I now see that I spent most my life in doing neither what I ought nor what I liked.'

For me, thinking of this passage (and the horror of coming to say "I now see that I have spent most of my life in doing neither what I ought nor what I liked") helps me feel very motivated to snap out of boring, sterile activities. It makes the consequences clearer, and, it gives the action of closing the site/app/etc a sense of thrilling defiance.
