Marie Forleo is an entrepreneur, writer, and speaker who is known for her online course, B-School, a 6-week online course that teaches entrepreneurs how to build and grow successful businesses.

Marie began as a life coach and soon started creating content online, including blog posts, videos, and podcasts. As her following grew, she decided to launch an online course to see what would happen.

In 2010, Marie launched B-School, which quickly became a huge success. The course teaches participants about business strategy, marketing, sales, and more. (Sound familiar?) Marie uses a combination of video lessons, workbooks, and live Q&A sessions to help her students learn and apply the concepts.

According to her website she’s had nearly 80,000 students and charges $2500 per student. 

Did you do the math? I did it three times because I couldn’t believe my eyes.

Granted, she probably didn’t charge $2500 in the beginning. But still, if you multiply 80,000 students times $2500 each you get…

... Okay, I’m back. I had to recheck my rechecking of the math.

Can you build a course?

Can you market a course?

Because if you can do those two things, then I believe you’ve got a shot at $200,000,000, too.

Marie has turned this single course into an entire career, appearing with Oprah, authoring a best-selling book and doing speaking engagements around the world.

And it all started with some simple content to begin building her audience, selling her course to those first subscribers and followers, collecting the testimonials and repeating the process.

Not to take anything away from Marie and her accomplishments, but if she can do it, then so can you.
