Monevator: I don’t think a net worth goal is the way to go either, but a lot of people put stock in a number (it’s an easy concept for a lot of people who are new to personal finance).

Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
Go hunting or foraging for food. You may need to invest in gear and permits, but if you already have these, this is an inexpensive way to get your own food. If you're ethically against the killing of animals, it's pretty easy to forage for food, depending on where you live. Just make sure to forage only for food whose origin and properties you are sure of. Getting sick or poisoned is never any fun.
Mow lawns or plow driveways. If you’re willing to mow yards or shovel or plow snow in the winter, you could easily start your own snow removal and lawn mowing business on the side. While you can usually find work by reaching out to your local community via word-of-mouth, flyers, or online message boards, the website Plowz & Mowz allows you to set up an online profile and reach more customers in your area.
Market your course: The beauty of using a course to make money online is that you can continue to sell it for as long as you’d like. Look for niche communities on Facebook, LinkedIn, or Reddit that might benefit from your content. Guest post on relevant blogs and sites. Look for anywhere you might be able to get in front of the right people. With just a few hours a month you can continue to generate sales.
