A few people who started their own YouTube channel when the video-sharing site was in its nascent stage are now millionaires. Now that YouTube has become immensely popular with hordes of people running their own channels, making a million dollars is considerably more difficult, but earning a respectable sum of money is still possible.

A lot of people these days are moving towards the two job concept. Amongst the people i know who have applied this in their life; the primary reason is that the 9 to 5 job pays their bills, lets the fire burning in the kitchen, and the second job is where their passion lies.

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.
