New Year, new resolutions, and we should want to increase our income in 2022. Not only that, but you can supplement your income with passive income. Our time is unimportant when it comes to passive income. This means we can spend our time once and make money from the source again and again. For instance, writing a book can earn me money while I do something else. Passive income is based on this principle.
