Committment

Improving at golf takes time and some work.  One of the areas I see students struggle with is committment.  They have some success on the range and then go to the course and if they don't instantly see improvement they either doubt or fall back to their old flawed swing. 
What I would like to see more of is a sense of letting go of what the result might be.  If you put your focus on what it takes to hit a good shot that's all you can do.  You can't control the rest.  The focus might be a picture, feeling or thought but if you give 100% to the process then at the end of the day you can't fault outcome.
