Books & Courses = $420,000+ Side Hustle

  • Serial Entrepreneur
  • $420,000+ estimated revenue from books and courses

Hassan Osman is an author who has managed to publish over 20 books and 12 online courses while working a full-time job 💪

He recently tweeted

Everything I know about creating on the side in 5 simple ideas

All on the side while working a demanding full-time job (and not sacrificing family time)

Best I can tell, he’s been working this side-hustle for 10+ years. 

His courses have been taken by 320K+ students and his books have apparently had 100K+ readers.

Hassan sells the courses via Udemy and the books via Amazon.

Even if he made only $1 for each sale – a very conservative estimate – that would be $420K+ he’s earned on the side 🤯

His first piece of advice is a concept coined by Gary V: Document, Don’t Create.

Hassan writes…

I’ve published in multiple categories: 

Management: I just documented what I already knew about managing virtual & hybrid teams, and about leading people

Travel: I just documented my weekend family trips to Rome, Paris, London, and most recently, Montreal

Authorship: I just documented how I wrote, published, and marketed all my books

With that in mind, what knowledge or experience could you document or package up in a guide, ebook or course? 🤔

Hassan continues…

you probably won’t have a lot of time to market and promote your stuff.

I use two primary platforms:

• Amazon for books
• Udemy for courses

… Although both platforms take a higher margin cut (and they have several other disadvantages), they make up for it by marketing my books & courses on my behalf so that I can focus on creating.

Hassan also repurposes a lot of the content he creates…

Do the hard work once, and then repurpose (and reuse).

For example, he turned one book he wrote into 👇

  • An audiobook
  • A webinar
  • A paid course
  • A podcast
  • Blog posts
  • Social media content

He later adds…

The key to publishing on the side is volume.

I don’t go all in on one book or one course…

Focusing on volume makes me a bit more immune to failure

Lastly, Hassan says the most important thing is to enjoy what you’re doing 😍

What I do is super-fun for me. I genuinely enjoy the process of writing books… If I was creating just for the sake of starting a side hustle, I would have quit 10 years ago.
