So many people dream of writing a book, but never go through with it. Yet no matter what, I’m sure you have experience and value you could give through writing a book. By packaging your skills and knowledge into a downloadable eBook that helps people learn a skill, advance their careers, or start a businesses, you can change someone’s life and even make good money online. You'll just need to employ an easy tool like Sellfy in order to quickly sell PDF files (like an eBook) to your readers.
If you're interested in online marketing, setup email software and create a lead magnet that you can use in your sales funnel. Then, build up that list. It's often said that you can expect to earn about $1 per subscriber per month. If you have a list of 10,000 subscribers, that means you can earn roughly around $10,000 per month. You will need to deliver value and not pitch them on every email, but it is a very achievable goal in a short period.
