How much should you learn before you make your first investment?

[Ben Feder]

How much do you need to know about the REI process before diving in? On one side, I feel like if you don't know enough then you'll be investing without proper knowledge/won't be prepared, but on the other side, I feel there comes a point where you just need to take action or you won't ever make any deals. What is that point where you need to draw a line and say, "I've learned enough. I can start investing now." (and obviously continue to build upon your knowledge at that point)
