What don't many people understand?

They don't understand that only rabbits breed quickly, while lasting results in life require discipline and regularity. You can't start making millions in a snap if you don't change your mindset, and that takes determination and time. You can't start speaking a foreign language by taking one class. You can't get rid of psychological problems by going to counseling a couple or three times. So - what does "fast" mean? Fast is actually slow but steady. And the "I want it all at once" thinking is a dead end.
