"I also like the strategy of temporarily suspending your disbelief and throwing yourself headlong into something for a while, allowing your emotional state to be as if you were 100% confident" All work happens because of this essentially. A result of over-zealousness. Irrational thoughts that keep you going that extra mile at 2 am because you really believe in an idea (more than it ought to be believed many times). If people didn't feel irrationally strong about things, then nothing meaningful (sometimes low probability of success, but high expected value as the author mentions) would get done.
