5) Determine What Income Level Will Make You Happy. Think back to when you made little to no income as a student. Now think back to the days when you just got started in your career. Were you happy then? Now go over every single year you got a raise or made more money doing something else. How did your happiness change at all, if any? Everybody has a different level of income that will bring maximum happiness due to different desires, needs, and living arrangements. It’s up to you to find out your optimum income level.
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.
