If you're familiar enough with programming to learn C in a day, you can learn assembly in a couple hours. It's really not that complicated. You can copy to/from memory addresses to local temp variable containers that are various sizes of bits (registers), you can do various math operations on those bits in those registers, you can compare those registers and test that comparison, and you can jump from the current point in the code to any other point by label or address (go-to). Sometimes operations will result in other registers you can check to see if something happened (overflow). The OS will provide some interrupts to do some base things as interrupts such as IO. If you didn't know how to code in assembly already, you now know enough to do everything C can do with a simple reference sheet. All the extra boilerplate (such as program segments and where to store costants such as what the 'strings' program sees in a binary) you can read two to three pages to explain what you need for whatever OS you're on. Assembly isn't hard, it's just tedious.
