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.

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.

Even if your app business idea doesn't pan out to be a best-seller, you'll still pick up valuable skills.
