To do that, you have to harbor a few fundamental guiding principles in your mind. Today, if you're at all serious about generating a full-time income (and more) from your online activities, then you need to focus on passive income as opposed to active income. Sure, the active income will help you survive. That's the scarcity mentality at play. But it's the passive income ideas that will help you thrive.

Once you have that problem or need nailed, the next step is to validate that idea and make sure you’ve actually got customers who will pay for it. This means building a minimum viable product, getting objective feedback from real customers, incorporating updates, testing the market for demand, and getting pricing feedback to ensure there’s enough of a margin between your costs and what consumers are willing to pay.
Note:  There are dozens of other survey sites out there. These just happen to be the more well-known ones that have a reputation for paying out in a timely manner and not having impossible standards for cashing out. As always, be careful with your personal information. I recommend using an entirely separate email address for survey sites so they don’t clutter your inbox.

Websites such as Upwork, Fiverr and Freelancer offer opportunities to do a variety of freelance jobs, such as writing, programming, design, marketing, data entry and being a virtual assistant. Fluent in a second language? Check sites such as Gengo or One Hour Translation, or drum up business through a site of your own. No matter what kind of freelancing you do, keep track of the going rate for the kind of work you provide so you know if you’re charging too much or too little. Learn how to get started on Upwork.
In the past few years, craft marketplaces have popped up all over the Internet and offer a place where you can sell your handy work to those who appreciate handmade items. Etsy is the most popular marketplace out there. You can create your own web store on this site and list your handmade crafts, vintage items, and craft supplies. There are plenty of other sites on the web that cater to arts and crafts of all types. You can earn some extra money while enjoying your favorite hobbies.
