Even with an atrocious golf swing, if one repeats their tempo, club face timing, and swing path, they will be able to figure out, in the moment, how to properly hit a golf ball for them. Within this process, you are making these minuscule adjustments, both subconsciously and consciously, based off of the most recent shot, which in turn enables you to hit the next one slightly better. In doing this, by the end of the session you will be striping every ball, but doest this represent any improvement in your game? Absolutely not! 
One of my favorite players of all-time is Ben Hogan. He classifies this process above as "range rhythm". Fundamentally, you are creating a process of short-term memory and are adding no value to your golf game. The problem is that it is so fascinating to just stand there and bang ball after ball, it begins to lure your ego into a place of content. Let's be honest, what human doesn't enjoy hitting a golf shot exactly how they wanted to? When in reality, it's not getting you any closer to your goal of PLAYING better golf. 
Instead, what is really happening is you creating this space in your mind of faux expectations. What is a faux expectation you ask? It is when you hit the same shot over and over and over again and build confidence that you will be able to do it when you are on the golf course. BUT since it was only one golf shot, and that golf shot doesn't present itself until the 15th hole and by that point you are already mentally drained. 
I rarely see the average golfer try and replicate the golf course while on the driving range. Golf is the only sport where you don't practice on the same field as the game. You have to create an environment that creates more pressure than you will face on the course. The only way to create maximum enjoyment and freedom on the course is to create a maximum amount of pressure while practicing. No matter your skill level, this pressure can be created by increasing focus and creating more specific targets. 
I know......it is easy for me to sit here and say this....right? I also lived it. I understand what it is like to be aimless on the range for hours that turned into months that turned into years that resulted in the same lame ass disappointing scores. It wasn't until there was intent, pressure, and execution added to my driving range sessions that I began to grow as a player. 

You have to be willing to be uncomfortable. Put yourself to the test. Better to do it when there is no consequence than when you have to pull another ball out of the bag!
