Fur. (Not listening to anything atm)

How does one fur? I added notes here (this was done based on a tutorial), but I still don't know how to fur properly. ;^; 
I've got to get better, I've got to hit it big, I've got to get better, c'mon chant it with me! 

On another note-- if anyone is using CSP (Clip Studio Paint), this is a breakdown of how I shade... essentially. xD Again; how does one draw fur? I still have no idea.
