If you're a whiz at social media, having accumulated many followers on Twitter, Instagram, and similar sites, you may be able to make money by offering your savvy skills to small businesses -- and perhaps even large ones. Many companies want to develop and capitalize on social media followings, but they don't know how to go about it. You might get paid for managing their accounts and posting to them regularly.
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. Check out Indeed, Learn4Good and Remote.co for remote english tutoring jobs or sign up on a specialized site like VerbalPlanet or Chegg Tutors.
@Philip Taylor So by what you’re saying, I can be an unaccredited doctor or surgeon for someone (for example) but do it at a much lower rate than the accredited doctors and surgeons. Since I know what a scalpel is and I wear rubber gloves, I’m a doctor. So, I don’t have to have to respect the profession of medical science at all since I think I know what I’m doing and just go for it.
There are various ways to make money with games. Obviously, there's gambling, as poker, blackjack, and other games offer winnings -- though those winnings exist because of many other players' losings. A safer bet, if you're a dedicated gamer, is to try to get paid for play-testing new games. A little Googling might turn up some possibilities to investigate. At sites such as BoardGameGeek.com or VideoGameGeek.com, you could look up game designers and publishers to contact.
Are you organized, detailed, and actually enjoy planning out activities? Then why not give event planning a try? As an event planner, it would be your duty to find a venue, caterer, and entertainment for everything ranging from birthday parties to office parties and networking events. You might want to consider making one type of event planning your specialty--such as wedding planning, which would probably be a full-time job on it's own.
For anyone who has capped at their current job, it could be time to look for another. If your salary is capped, it typically means that you are an expert for your current job, and the company can’t pay you anymore money for doing the same job. Take this as a sign to better utilize your skills at a more challenging, and subsequently higher paying job.
