Also, if you are a normal person, your first attempt at learning assembly probably won't go well. Most likely in 28 days, you'll look at day 3 and freak, but you'll think you understand it so after you read it, you'll move on. Then when you start getting up around day 6, you'll realize you have no idea what you're doing and you'll take a break.
But, when you come back from this break, that is when you will finally succeed and begin to write assembly programs.
Heh, that's the best description of the Assembly learning curve you can give. It's a lot like riding a bicycle. No one does it the first time and it requires completely different ways of movement than walking. However, it's a lot faster and you can go pretty much anywhere you can go on foot with a bike.
