The Challenging 'False-Hope Syndrome'.
Documented cases of this psychological problem have indicated that the issue might be the result of setting expectations too high. Overconfidence might hinder your ability to succeed. ‘Pie In The Sky’ goals can become obstructionary and counterproductive.
Think about how you practise. Start with the putter and work up from there. Try to set small and more easily measurable goals as your foundation. You will remember that “A Chip Is A Putt With A Hop!” The ‘Pre-Shot Routines’ are very similar! Having more attainable goals helps you feel more likely to improve. (see ‘Micro & Macro’)
