Firstly, let me start by saying that money does not grow on trees. Yes, you read it right. There is no way for you to make money without putting in genuine work that can repeatedly generate income for you whilst you can focus on other things.
As a simple definition, passive income is income generated by providing value that is not directly tied to your own time.
Let me break this down a bit further. To get paid money by someone, that person must see or find value in whatever you are offering. To provide value to that someone, some kind of work or task must have been executed. This means that in order for you to make passive income you still need to do some work, and often do it without immediate returns, until it reaches a customer or multiple customers, where they can exchange money for the value you are providing them with.
There are various ways for one to earn passive income and these income streams vary in intensity of work, grind, hustle, earning values and some also come with risk. In most cases, one has to have a consistent offering to ensure that value given is perceived as high. This will retain higher customer engagement and returns.
