Create a product that earns income by itself
Selling your services doesn’t have to be an hourly thing. For example, there are products you can create that will bring some income without you having to dedicate much time to making them, especially if it’s an online product.
Say you create a training program, a software app, or an ebook. You can then sell it online and make money without investing too much of your precious time. That way, you’ll have an income source that doesn’t depend on you reaching any deadlines.
