One of the easiest ways to get exposure to dividend stocks is to buy ETFs like DVY, VYM, and NOBL or index funds. You can also pay an algorithmic advisor like Wealthfront to automatically invest your money for you at a low fee. In the long run, it is very hard to outperform any index, therefore, the key is to pay the lowest fees possible while being invested in the market. Wealthfront charges $0 in fees for the first $15,000 and only 0.25% for any money over $10,000. Invest your idle money cheaply, instead of letting it lose purchasing power due to inflation. The key is to invest regularly.
Some good writing here! I am a realtor myself and frequently get in touch with clients that consider buying a realty estate a conservative of investing. I once heard of a transport company in Vienna, Austria, which focused their entire profit on buying eventually every house available in the downtown for about 80 years. That must be some of a passive income!

While stocks are terrific income producers, they can be volatile. Every few years, the stock market tends to stagnate or drop for a while before recovering, and that can be problematic if you were counting on your stocks having a certain value at a certain time. One way to lock in an income stream is by buying a fixed annuity (as opposed to variable or indexed annuities, which can have steep fees and overly restrictive terms). Annuity contracts will be more generous when interest rates are higher, but here's how much income they might deliver at recent rates:
Another great way to get started is to identify an area of interest you have. For instance, Robert Duff has been successful in building passive income by selling books on Amazon. Then, go out and start talking to people. Ask them, “What are you struggling with right now? What are your biggest pains? What’s something you wish existed that doesn’t?” That’ll give you some ideas about where to get started.

The reason I consider dividends artificial and believe they don’t matter is because you can just as easily reinvest your dividends. If a stock is worth $100/share, I don’t care if it issues a $1/share dividend or if the share price instead increases to $101/share – either way, I have the same amount of money, because there’s no difference to my net worth whether I take the dividend or sell part of a stock.
Our most significant source of income is Mrs. RB40’s earned income, but that will change when she retires in a few years. Luckily, our expenses are at a reasonable level and we don’t need to replace her whole income to keep the same lifestyle. For 2015, our other sources of income just about covered our cost of living. The high-tech antitrust settlement gave us a shove to get over the finish line. That’s just a one off, though. I’m not too worried because there are other ways to generate some income to make up for Mrs. RB40’s paychecks. Here are some of them.

For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
