Write and sell an e-book
If you have a passion or skill for writing, consider writing an e-book. Books that help people about a technical topic often sell well, professionals say. You can sell your books online through various platforms including Amazon’s Kindle programme, which enables you to stay connected with a large number of people interested in digital books. Audiobooks are also becoming popular as more and more people are diverting to audio and visuals when dealing with subjects that seem technical. But experts often recommend doing an e-book first before turning it into an audiobook and subsequently selling it.
