Invest focus in the controllables you can train
The speaker lists things he believes golfers can learn to control as skills: self-talk, body language, attitude, decisions, preparation, responses, calming, routines, and poise, which he defines as not going too high or too low while still playing with emotion and passion. He says that when golfers invest focus in these controllables they tend to get more mentally strong and more in control, and build more grounded, sustainable versions of confidence.
