While some people tend to use a savings account at the same bank where they have their checking account, make sure it's a high-interest one, not just a convenient one. "For short-term savings that you have parked in a savings account for easy access, you can often make more money just by researching whether you're getting the best interest rate," Goudreau says. "While many traditional banks offer as little as 0.1% interest on savings, online banks tend to offer higher interest rates. By switching to an account that offers 1% interest or more, you would be making 10 times as much just by moving the money."

While it is important to find something that you love to do and turn it into a money making business, you do have to be cognizant of the return as you pointed out. There are many opportunities that I found and tried out that at the time seemed great. But when I took a step back, I realized that I was working a lot for very little income whereas other things I love doing brought in much more money.
Are you sitting at home and wondering how you can bring a little bit more money into your home?

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.
