playing golf on a golf course in cloudy weather

I see so many golfers fail to reach their potential because they do not put in the right amount of effort. Take for example your practice time. It may be too little or too easy. Perhaps not challenging enough to develop the necessary technical skills. You need to make it hard enough to experience failure and this develop perseverance. Perseverance offers no guarantees but without it, it is more likely you will not succeed. What things can you do to put in the effort and develop the determination to succeed?
