Publishing is dead; long live the e-reader! Now that anyone can have their work e-published, it is possible for anyone to make a fortune off their writing. The biggest recent example is the 50 Shades of Grey trilogy, but there are many authors taking advantage of the ease of e-publishing. If you love to write and are willing to do your own promotion (and having a blog can really help in that case), writing an e-book is an excellent way to make money at home.
Then you can move into more actionable online courses like Modern Web Design on CreativeLive and Learn Web Design and Profitable Freelancing on Udemy will teach you everything from foundational web design knowledge to earning your first freelance income as a web designer. On top of that, you can take even more immersive courses and learning experiences with access to direct instructor feedback and personal mentorship with platforms like Treehouse, LinkedIn Learning and General Assembly to get up-to-speed even quicker with this career path and listen to my podcast interview with Ian Paget about how to become a freelance designer as a side business idea.
If you have a way with words and know how to make the keyword-friendly, beautifully designed, SEO-optimized landing pages, why not charge other companies for your services and turn it into a money-making side business idea? Even a short landing page is worth a couple hundred bucks in most cases, and so much more if you know how to pitch your prospects well. If you want to get started with your business idea of becoming a landing page specialist or freelance copywriter, check out Len Smith and Sean Kaye's awesome course on Udemy, Copywriting Secrets: How to Write Copy That Sells.
