How Do I Begin?

[Dat Chung]

First and foremost, how do I begin? I'm 20 years old, work an hourly job, and have very little saved up. I was looking online, and getting a fourplex, renting out three of the spaces and living in one of them, and creating a positive cash flow sounds nice, but the question is.. how? How do I get started, and where do I begin? Do I need to get a license? If there is another thread that answers my questions, please feel free to include! Thank you for your time. :)
