I think this came from Garden of Emunah: There are two types of people on a bus. One is constantly watching the driver, making sure hes going the right way, driving safely etc. The other is sitting with his nose in a book, not paying the least bit of attention to the driver. We’re going through this world, and Hashem is driving, we could do our own thing, and not worry, and trust that Hashem knows what Hes doing, and He’ll get us to the right place, or constantly do our own checking. At the end of the ride, both passengers end up where they started out going. One is just a nervous wreck.
