Telephone lessons aside, distance learning provides a low rate of success, as it’s difficult to monitor attempts made and their quality. Also missing is the special atmosphere created when groups of real practitioners gather. This atmosphere greatly facilitates learning, in addition to making it easier and more interesting.
Distance learning can yield a high return-on-investment thanks to the inherently-unlimited group sizes of formats like webinars and group e-mails. Many people can join thanks to the lack of geographical limitations. An instructor can have thousands of students scattered across dozens of countries while living in a small town in some backwater. The problem, however, is that people don’t pay as readily for lessons that aren’t face-to-face, which is why distance learning usually pays substantially less than in-person instruction. On the other hand, minimal expenses (the sole expense might be advertising, and that’s only if it’s paid) and the unbridled, vast potential of such forms of instruction (as well as the potential of the Internet itself) make distance learning most promising.
Take, for example, a one-time webinar. It would be realistic to enroll 1,000 people at a price of 1% the national average monthly income. You would bring in 10 times the average monthly salary and have at least half a year’s average pay left over after taxes and other expenses – not bad for work performed while wearing your slippers.
