I would say that cottonwood's response was a great one,
but if you have an internet business that is doing 6 figures,
I'd say you were big enough to hire someone to manage
the day to day business operations, (taking orders and fulfilling
them) so that you could continue teaching, or continue your education
to a higher level, or even develop a way to teach online, thereby spreading
your teaching skills to more students.

Many universities are moving to online curriculums, because
of cost (to student and institiution) and I see it as the wave
of the future in education. Currently there are many technical
skills that can be obtained through online study, and eventually
I expect nearly all major universities to offer classes and even
degrees online.
