Anyone have an idea about passive income?

Passive income is earning some amount while doing almost nothing. Yes, I read about rental income, it is a form of passive income. Speaking about online passive income, we can consider investing in shares, stock or bonds as passive. We can also try blogging and other writing sites. Although it may take some time, having an established site can make us money even if we don't work for a certain period of time.

It is heavy to earn a living from passive income. Probably a rent, offline income, young retirement are passive income ideas. Especially me, when my parents were alive we had a flat under rent and it was a good income period of time. This is my experience.

I have no idea about this.
