Everyone (even kids and retirees) need to have some level of technical know-how to stay competitive and appreciate the marvels of the digital age. Just observe how learning sites like Codecademy, Treehouse, and Udacity continue to grow and you’ll understand the urgency of getting computer training for our generation (thus making it a great business idea to train others if you already have the skills). If you’re a techie, you can cash in on this need by offering lessons and tutorials within your neighborhood or across cyberspace through portals like YouTube or Udemy as a side business idea. You can even set up your own tutorial site with an interface for online payments.

Or, if you’d prefer more something more editorial and less salesy, you can find that, too. Media companies (including Entrepreneur) offer digital writing and editing positions for the digital publication, which essentially can be accomplished from anywhere in the world -- as long as you have an internet connection. In fact, we have some writers at Entrepreneur who work from Paris or their home offices instead of the office in New York City.

Have an extra room in the house? Try renting it out on Airbnb.com. According to Smart Asset, you can pay up to 81% of your rent by listing one room in a two-bedroom home. If you're really looking to ring in the cash, renting out a private home or apartment is the way to go. According to Smart Asset's findings, rates for full apartments are significantly higher than those for just rooms, with annual profits ranging from $15,000 to $31,000 for a two-bedroom apartment.
It’s an excellent opportunity to offer technical training courses that teach people how to learn a much-needed skill, or accomplish an important task. It could also prove to be an important testing ground for your educational courses. If you are able to market your course on the site, against direct competition, you may be able to direct marketing to the general public, using a website, videos, or even an affiliate marketing program.
Robo-advisors are diversified investment accounts that are automatically managed by a computer algorithm (as opposed to a human money manager). If you want to invest, but don’t have the money, or don’t want to invest with a money manager, robo-advisors are for you! Robo-advisors make investing easier—and cheaper—so they’re perfect for new investors.
