It's recommended to dedicate the majority of your practice time to working on your swing mechanics, as this is the foundation of your game. Additionally, spend time working on your short game, putting, and course management. Also, make sure to include physical fitness and mental conditioning into your schedule. A good breakdown would be 30-40% swing mechanics, 20-30% short game, 20-30% putting, and 10-20% course management, physical fitness and mental conditioning.
