Parlay your math, science, foreign-language or test-prep expertise into a lucrative side gig by becoming a private tutor. You can tutor people online or in-person. What you charge can depend on your experience, expertise and what’s in demand. To get started, see what types of tutors are needed on Craigslist, or create a profile on sites like Tutor.com or Care.com. You can also advertise your services at local schools and community centers.
Identify a consumer need. Pinpoint a specific problem or inconvenience that many consumers have. Be as precise about the issue as you can. Write down the issue and consider what produce or service might solve this problem. This can be a physical thing or it might be a service you offer. For example, you could build a product like a car or you could provide a service where you repair cars.
