Fluent speaking is by far the hardest part of learning a language, and that's not something I'm trying to do. Being able to recognize, say, a verb form is much easier than having to remember it on your own and then use it properly.
A good point! Much easier to develop receptive skills than productive ones, especially reading. It also seems like people retain those skills for much longer - I know a lot of people who studied French in school years ago and couldn't get beyond "je m'appelle" but can still understand some written bits.
