Stocks, bonds, 401(k)s, annuities, etc. are great ways to earn passive income. If you're not financially savvy, you'll want to hire a financial advisor who'll help you choose the right investments for you. You may want to take a couple of finance classes to understand what your advisor is speaking about when he/she recommends an investment strategy. Done right, investments can pay off for years.

Starting a blog is one of the most popular side hustles to earn online income. This is because whether you have 10 people or 10 million reading your content, the amount of your effort to write an article is the same. Websites have low start-up costs and you can literally buy your domain, launch your site and have a few pages created in less than an hour. You won’t start making money right away, but you will be building towards that first $1 of income. 

How to Monetize: Affiliate marketing works well when you discuss products on your blog. For our fish tank blog, we would link to all the things you need to buy for an aquarium and then when people click on that link and buy that item (and other items they purchase with it with some exceptions) you get a percentage of the purchase. Amazon Associates is the best-known affiliate marketing program, but there are others like Impact Radius, ShareASale, Commission Junction, ClickBank and Rakuten too.
I think the holy grail of financial freedom is having so many passive income. This way you will never worry about your financial needs because everything is taken care of your assets.

Creating passive income is the key to retiring, especially retiring early. If you want to retire early with the stock market you will have to save a huge amount of money, because that money has to last so long and retirement calculators depend on you using your investment to fund your life. With passive income you will have income coming in as long as you own the investment, without every eating away at the principle invested. Creating passive income may take more work than investing in the stock market, but I think it is well worth the extra effort!
