Kevin discipline is the key and that goes hand in hand with consitency, for a recent example. I was hired as a maintenance technician where I work, that is what I do (did), I am good at what I do, or so says my super. Last night I was asked to help out and do some production work (arrgh!), but I did the first hour sucked bad because I didn't have a "system", the second hour I developed a system (til one of the other guys messed me up, by "helping"), anyway for the next three hours using my system, I became very consistent and was filling 2 boxes a minute as opposed to one box every three minutes, as before.
A lot of folks disagree with the idea of a routine, but when you do the same basic thing day in and day out, you get good at it, the same goes for throwing pointed objects, you develop a system that works for you, and do the same thing again and again you may have to make minor adjustments from time to time, but in general the system works. For a new pointy thing you are throwing you will have to build a system and stick to it, til you get good at it, then keep practicing with the old and new object in some sort of rotation, before you know it you will be getting two sticks with one throw, LOL. that is my 2 cents worth.
