Experience...but I was thinking about posting something similar and I would have to say for me patience.
You can be the most patient person in the world, but without intellegence of the animal your hunting your not going to see anything.... I doubt you could wait patiently at the top of the empire state building and see your Freak nasty walk by.... make sense?
But it goes the other way too. you can be intellegent and know right where that deer is gonna be.... but theres no way to know when.
