Fundamentals of Putting , and Driving

there's a lot to that phrase.
I'm not a great player but I apply the lessons I received from Geoff and John Lissaman.
I have my own way of expressing my concept of what is happening when you throw.
First there are two or more factors involved in throwing. The first two are at least somewhat
within your control.

They are the disc and your body. With a new or broken in disc you can count on it to perform the same every time it is thrown exactly the same. Your body and throwing are up to you and both in your control and the first variable ( One of the things the Lissamans
stressed reducing) So picture two graphs. One depicting the ideal flight of the disc. And the other depicting what your body is trained to do. This variable is about fitness and level of training. The more you train and practice the more you gain control of your throw. Picture the two graphs together. The point where they converge is the sweet spot you might say. But the sweet spot is suppose to be in the basket but for you it's out there twenty feet to the left.

You must learn to adjust the main variable within your control, You.
Start by adopting a posture and stance that allow you to best utilize your current skills.
There are many to choose from and most any( at least the ones the pros use) are good to adopt. But start out with one or two at most and perfect your abilities with those before you try to learn too much variety. Once you have a method down you will begin to develop a familiarity with what your body is cape-able of. This is a great confidence builder and in time it will come naturally. . Once you feel that confidence your game will improve.

The human body is an amazing thing. It's easy to find yourself feeling let's say less than par the morning after a great party or whatever Your body is unlikely to respond to your requests for those motor skills like walking and talking. But you will find that if you have those motions perfected then just like finding your way to bed when half blind, you can learn to throw a 70' putt. It's the same as with any physically demanding discipline.

I can't put enough emphasis on practice. Continually evaluate yourself and practice both the shots you need to improve on and the most common shots. Work on your weak points twice as much as what you have down. Spend twenty minutes a day putting.
Once you are comfortable with your throw your mind will be free to focus. As all the distractions slip away you will find it easy to focus on a spot and follow through
without effort.
Then comes all the other variables
