How do I start with no money down?

[Erick Sanchez]

Hey I'm 20 years old. I'm not going to college. I have no money in my savings. But I really want to get into real estate. I find it very exciting! What is a good way to start investing with no money down? I'm interested in buying duplex's or triplex's. Should I start with a single family home? Is there step by step instructions I need to follow? What problems will I encounter and how do I overcome them? I know i'm asking so many questions, but I'm hungry for knowledge!
