It’s not the sort of online money making opportunity that’s covered in glory, but everyone needs a set of eyes to make sure the numbers add up at the end of the year. Every business and most individuals need someone to help prepare tax returns, especially time or resource-strapped small business owners. The Income Tax School provides an array of training programs that'll certify you with tax prep in as little as 10 weeks, and once tax season rolls around you'll be able to charge an average of $229 per return as a freelance tax preparer with this side business idea, reports CNBC.
My use of the word "secrets" in the title of this article might have brought you here hoping for a guaranteed, almost magical solution to make you wealthy. There isn't one. The fundamental objectives are simple: Make more than you spend, and use the excess to invest wisely. How you invest is up to you (with a few caveats below), but the obvious goal is to make investments that have a high likelihood of making you more money in the future. That's it. The ways to achieve this are by making more money, spending less, and investing more wisely.
Don't put all your trust in Social Security. While it's a good bet that Social Security will continue to work for the next 20 or so years, some data suggest that if Congress doesn't radically alter the system — either by raising taxes or reducing benefits — Social Security won't be available in its current form. It is probable, however, that Congress will act to "fix" Social Security. In any event, Social Security was never designed to be the only resource for retirees in their later years. That makes it all the more important that you save and invest for the future.

Stay rich. It's hard to get rich, but it's even harder to stay rich. Your wealth is always going to be affected by the market, and the market has its ups and downs. If you get too comfortable when times are good, you'll quickly drop back to square one when the market hits a slump. If you get a promotion or a raise, or if your ROI goes up a percentage point, don't spend the extra. Save it for when business is slow and your ROI goes down two percentage points.
Now, I know what you’re thinking. Most of the software and apps you use on a regular basis are made by massive companies or established development studios. Well, yes. But many successful apps, particularly those in the Apple and Google stores, are created and marketed by individuals and small businesses. In fact, independent developers made $20 billion in the App Store in 2016 alone.

Before you start regularly saving and investing money, it's usually a good idea to pay down any debts you may have accumulated. Credit card debt, student debt, and even car loans can carry heavy interest rates that drag you down, demanding monthly installments that chip away at your revenue while racking up additional interest and penalties that take away even more money from your future self. Don't let this eat away at your potential; make it a first-line priority to get rid of your debt as soon as possible.
We've all heard the saying. Pay yourself first. But how many people follow it? The truth is that most of the world lives with a scarcity mentality. They go paycheck to paycheck, petrified of what might occur if they get sick or lose their job or something else traumatic happens. The truth is that if you don't pay yourself first, you'll never be able to get rich. It's part of having an abundant mindset and should be prioritized at all costs.
There is a simple fact that many people miss: you will never grow wealthy if you spend everything you earn. Regardless of how much money you earn, you need to put some aside in savings. Having a cash cushion is nice because it helps you prepare for unexpected expenses and helps you avoid debt. But there is another reason that saving money is important – because of taxes and other factors, money saved is worth more than money earned!
