Start by playing nine holes with three to five clubs, carrying your own bag, and timing the round from first shot to final putt. Keep the first attempt relaxed: the goal is learning how golf decisions change when you move continuously.
Choose a quiet tee time and tell the course what you are doing. A wide-open nine is better than forcing the format into a crowded afternoon.
Bring fewer clubs than you think you need. Most first rounds work well with a driver or hybrid, a mid iron, a wedge, and a putter.
