Start Early: Fixing your old habits isn't always easy. Start early so you can spend the late winter training your new skill, not fixing your swing last minute.
Build a Routine: Book out your golf lessons every week or every other week. Even a monthly meeting works well if it holds you accountable.
Set Goals: Decide what your "Non-Negotiable" is for the year. It could improve 1 major area that is a frustration, what would it be? When you look back in the spring, at least you can say this got better.
Creative Practice: Hitting balls at the Dome or Simulator is great. But don't underestimate practice swings at home and even mental reps on your new swing as you are trying to fall asleep.
Don't Forget Short Game: Using some of your lesson time on the short game can be very useful. Work on your mechanics to get GREAT CONTACT. Consistent contact will easily translate to distance control when you do get a chance to practice more outside.
