Next time you are at the range practicing your swing, make sure you practice with a good attitude. A good positive attitude is something you can cultivate overtime. It's ok to get upset but when you do, step back and take a deep breathe so you don't take that negative energy into the next shot. When you practice good fundamentals along with a good attitude, they both become second nature over time. It's truly a fun way to play golf when you not only have a trustworthy swing but also a positive mindset on auto-pilot.
