If you love to write and have specific topic knowledge, you could earn money by starting a blog. While there are some overhead and time without making any money when you start a blog, you can build a significant passive income on as little as a few hours per week.
After you create your profile, you simply wait for it to be approved, then get started driving. While driving for a rideshare company won't make you rich, it will allow you to set your schedule and start earning money quickly.
If driving people around isn't for you, you can consider delivering food for them instead. Companies like DoorDash and Instacart will allow people to sign up on their apps to deliver food to people in your area.
