Driving for one of the two globally expanding app-centric taxi alternative services, Uber or Lyft can still be a fairly lucrative way to earn money as a side business idea on nights and weekends—working only when you want. But before you dive head first into this side business idea, do your homework and calculate the costs of extra gas, mileage, tires, wear & tear and usage on your vehicle—it's not a guaranteed business idea that'll turn a huge profit every weekend.
A friend’s son was a member of the Chess Club at his elementary school. He spent one day a week after school for an hour, learning how to play chess. His parents paid $40 for 8 weeks of this club. That money went to the leader who was teaching everyone how to play chess. He paid a small rental fee to the school, but everything after that cost was profit for him. This brilliant idea could be a side hustle for you on the weekends or evenings. This entrepreneur offered these services to four different schools, worked just an hour a day and was able to live on the money he made while going to college. This is definitely not limited to chess and could be offered at a local rec center, a church, or the library.

You can also sift through the countless ad-supported YouTube channels that teach just about anything from guitar strumming to 3D printing.
Now for the completely strange and unexpected: Jon Colgan, founder and CEO of fintech startup CellBreaker, used his background in sustainability to help finance his business. “I also studied sustainability in school and became enamored of using worms to compost. As a third revenue source, I sell worms,” he says. “I discovered that happy worm populations double every 90 days. My worms are always happy. So, I started selling worms and vermicompost on Craigslist and by word-of-mouth.”
