The first follows the startup path we outlined above: You have a disruptive idea for an app or piece of software, you validate the idea with real customers, and then raise money to hire developers or a development studio to build, launch, and scale your software. If you’ve done everything right, your software will be accepted to the Apple and Google Stores and you’ll make money every time someone downloads it or pays for a premium feature.
Market your course: The beauty of using a course to make money online is that you can continue to sell it for as long as you’d like. Look for niche communities on Facebook, LinkedIn, or Reddit that might benefit from your content. Guest blogging on relevant sites. Look for anywhere you might be able to get in front of the right people. With just a few hours a month you can continue to generate sales.
There are loads of resources for making money online as an affiliate. You could source products from ClickBank, Commission Junction, Rakuten Marketing, Share-a-Sale, Impact Radius and many others. Plus, many of the larger companies have their own affiliate programs as well. Do your due diligence and find the right company with a relevant product or service to your audience that you can sell as an affiliate.
You can sell your ebooks through Amazon's Kindle program or Apple's iTunes Connect, which gives you access to a large majority of the digital-book reading market and the barriers for entry are incredibly low. You don't need to invest lots of money to make this happen, but you do need to invest lots of time, not only in writing the ebooks, but in marketing them as well.
Textbooks cost hundreds of dollars. It’s not uncommon for engineering and healthcare-related books to come in just below $1,000. But with the high cost of textbooks comes opportunity. Flipping them for profit. By using a service like BookScouter, you can instantly compare book prices across 44 different vendors. You pick the one that offers the best price and voila. Book sold.
Another great option is Acorns and my experience is that Acorns can make anyone an investor. It helps you start saving by rounding up your purchases on the debit or credit card of your choice. Then, every time you hit $5 in savings, Acorns invests your money in ETFs. Mighty convenient. Acorns cost $1, $2, or $3 per month depending on the plan you choose – making it a cheap option for young investors. Here’s our review of Acorns.
