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.
Remember the steps from point 2: Make more money, spend less, and invest wisely. Point 3 covered making more money, and this one covers spending less. Make a detailed budget for yourself based on your projected income and your current expenses. Set firm limits for your expenses, and keep a close eye on where most of your money goes--you might be surprised at some of the areas where you waste the most money. Once identified, you can start refining your budget to spend as little as possible, and funnel the rest into a savings or investment program.
Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)
