Read course reviews for popular courses. Look at the mediocre and low star reviews, what is it about the course that people want more of, use those weaknesses to your advantage. If everyone is complaining about the lack of the same thing, you should focus on adding it to your course. Be sure to look at what people loved about the course to ensure you also include favorable features. When creating an online course, look at the list of topic covered in it to ensure you include all of those topics in yours as well.
Write and publish an eBook. You don’t need a traditional publisher and financial backing to publish your own book anymore. In fact, Amazon.com makes it possible for you to publish your own eBook and sell it independently – with no financial investment on your part. And with Kindle eBook publishing, your book will appear on Kindle stores worldwide within 24-48 hours. Just be prepared to market it yourself on social media, your blog, or elsewhere if you expect to generate sales.
Landscape. Look for brush-clearing, mowing, or woodcutting jobs, some of which may land you regular customers. This can save you money at the same time: if you are hired to pick up pine needles, use them to mulch your roses, which will appreciate their acidity and smothering effect on weeds; if you are hired to cut and clear a fallen tree, use it to heat your house that winter.
