There is a saying in Russian, which could be translated as:
Take more, throw further, take a rest while it flies
Initially, it was applied to a manual digging with a shovel to demonstrate that this kind of work has nothing hard to understand and doesn't require to be very clever. Just take a shovel and dig. But nowadays it is often used to describe any kind of a dumb work. For example, when your boss is asking you to concentrate on quantity instead of quality. If you are a programmer, you need to write more code and doesn't matter, how fast it works and how much bugs it has; if you are selling cars, you need to call all the clients and propose them everything you have, and doesn't matter what impression they will have after, etc. So you can say about this: It is just a dumb work in "take more, throw further" style.
Is there an idiom in English or any other way to say this in one phrase?
