The great Warren Buffett said, “If you don't find a way to make money while you sleep, you will work until you die.”
He’s mostly right isn’t it. Try to create a passive income if possible.
That's right, however, passive income (apart from active income) must be had by everyone nowadays, the reason is quite simple, we don't know what will happen in our future, when we can't make money work while we sleep, it's difficult for us to do it enjoy a relaxed and comfortable old age, when we are old our bodies are no longer able to work hard so passive income is really needed to encourage us to do other productive things while enjoying the passive income.
