Paid Surveys

Side hustles for 21-year-olds are an excellent way to make extra money on the side. Even if you don’t have a traditional job, there are still numerous opportunities that can help to supplement your income while providing convenience and flexibility. One of those options is completing paid surveys online.

These surveys are one of the simplest ways to make money as a 21 year old, offering a great opportunity to earn some extra cash with minimal effort. Each survey normally pays between $2-5 and most can be done in 15 minutes or less. All you have to do is provide honest feedback on products, services and even your shopping habits.

Some of the best sites for taking online surveys include Swagbucks, Survey Junkie and InboxDollars. These websites offer users access to a wide range of daily surveys, including product tests and opinion polls on topics like politics, business and entertainment. They also give cashback for referring new members or completing tasks like website searches or creating content reviews.

Other platforms partner with market research companies that conduct research for big brands like Unilever or Gap so you could be asked to participate in focus groups or shop online and provide feedback about the experience afterwards in exchange for rewards points that you can cash out for PayPal credit or gift cards from your favorite retailers.

By dedicating just a few hours each week towards taking paid surveys, you can easily complement your income without leaving home!


If you’re a 21 year old looking for a side hustle to make some extra money, consider becoming a YouTuber. This option has been on the rise in recent years, and many people have become successful YouTubers. It does require work and dedication, but it is a great way to create your own online business and make some extra money.

Before creating a YouTube channel, log in with your Google account. This will allow you to access all the features YouTube offers and give you the ability to monetize your content if desired. Then decide on a topic for your channel – it can be about anything that interests you or likely will entertain viewers. Once your topic has been established, create video content around that topic – research relevant topics, film yourself talking about them, or create short informational videos with images or graphs as visuals. Make sure each video is edited with high-quality audio and video editing software as this can drastically improve how viewers perceive the overall quality of your production.

You can monetize certain videos once your channel reaches 1,000 subscribers and 4000 hours of watch time within 12 months through Google Adsense which runs ads before or during each video you post so that when viewers watch those ads they are paying for someone else’s services (including yours). As more people view your content throughout the year, more views bring more revenue (the money earned from advertisements between each respective view.) Post regularly – aim for at least 3 times per week as well as engaging comments on other YouTubers’ videos or social media platforms like Twitter/Instagram since they could potentially visit you back having noticed that interaction – this way you can extend yourself up to other view points outside of just who visited already subscribed (reaching out farther than just what’s already present). All in all, if done right – turns out creating engaging full-time YouTube content can potentially earn around $500-$3000 per month!

10 Tools Freelancers Should use to Increase Productivity


For ambitious 21-year-olds looking to make some extra cash while they figure out their career path, freelance writing provides a great side hustle. Freelance writing offers the freedom to work remotely and set your own schedule and rates.

Social media platforms are another great way to promote yourself and connect with potential clients; create an impressive portfolio website or blog that showcases some of your past work so people can quickly get an idea of who you are and what kind of services you offer.

When setting your rates as a freelancer it’s important not to undervalue yourself; price your services according to the industry standard rate for similar work but be sure not to overprice yourself either or risk losing out on potential clients due to cost.
