If you start working on a job, you will start receiving salary. Even when you are doing gigs, you will start receiving payment once you deliver your gig. Working in a job or going is active work, thus, they are active income sources. However, building passive income takes time and you need a lot of patience. Whether it's investing in stocks or starting a business, or creating something (for instance, blog,youtube, ebook, software, etc.) it might take months or even years before you see significant returns. Since it takes a lot of time and also requires hard work, not everyone is able to build a reliable passive income source.
