The major points are:

1. You can't judge the sanity of a strategy in a vacuum
2. Your mind may allocate resources differently to "terminal" and "instrumental" goals; leverage this
3. Certain false beliefs may improve productivity; consider cultivating them
4. Use compartmentalization to mitigate the negative effects of (3)
5. You already are a flawed system, expect that the optimal strategies will sometimes look weird
6. Certain quirks that look like flaws (such as compartmentalization) can be leveraged to your advantage

The insane thing is that you can think "I am going to swallow this placebo and feel better, even though I know it's a placebo" and it still works. Like I said, brains are weird.
