Better State of Mind, Better Golf
I believe your state of mind is a matter of choice. It is your own personal responsibility. It is made up of how we feel the emotions we have, the things we say to ourselves at any point in time. There are many components that make up our state and once you identify them you can establish a plan so those things can be reproduced. This way you will be able to experience great performances more often. To be a successful golfer you must blend and balance the technique and your mental approach. If you step onto the golf course with the intention of playing the game you will find it difficult to think about the mechanics.
When you are playing well your state of mind was almost completely free of mechanics, and you trusted your swing. Getting out of your own way, relying on your plan and processes will enable you less technically aware. Be a creative thinker, learn to problem solve, accept the outcome, allow yourself to move forward to make the shot anyway. These are all high quality mental attributes to train and develop both on and off the course.
No matter what it remains a game and enjoy the journey and the results will be.
