You have likely heard of subscription boxes such as Birchbox and Julep. While almost anyone can start a subscription box service, they can be incredibly labor-intensive and the profit margin usually isn’t so great for those operating on a small scale. Did you know you could start a subscription for your knowledge that’s almost pure profit? With sites like SubHub, you can offer a monthly membership offering anything from meal plans to workout plans to crocheting patterns and beyond. The sky is the limit. You do need to provide new content on a consistent schedule to keep your customers happy. But if there is something your friends are always looking to you for new ideas, you may have an easy little side business on your hands.
Teaching and tutoring English as a second language is a great way to make money online, not to mention open some doors for you to travel the world if you'd like. While full ESL (English as a Second Language) accreditation is recommended, as long as you’re a native speaker and have the ability to teach, there are people in countries such as Hong Kong or the UAE who are willing to pay upwards of $25/hr for you to tutor them English via Skype.
