Money is important. Of that, there can be no doubt. If you don't have enough for your basic needs, and a few necessary wants, there's no chance of you being content or happy in life. Everyone knows this of course. In fact, the need for money is why most of us go to work. But it’s never really enough is it? There's always some place we want to visit or some gadget that we want to buy but we can’t because of our barren bank accounts. So how do we get that extra bit of money that we're always craving for? Leveraging the power of the internet to generate a steady stream of passive income is the answer.
Domain names cannot be replicated. If one is taken, the only recourse would be to approach the owner to discuss a sale. While there are other variations you could choose, sometimes owning a certain domain (especially if it is attached to your business) can be worth the premium. Often, people will scout out domain names that are still available, buy them, and then sit on them in order to sell them down the road. Depending on who may want the domain down the road, you could sell it for a large markup.

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.
