For Gary, it was a “perfect storm”:

More than game improvement, I think the difference maker for Gary Woodland at Pebble Beach was his mental focus on one shot at a time, staying relaxed in the moment and concentration on his own golf game.

At the elite level, players understand the formula for success: Stay close, avoid big numbers, middle of the green, hit fairways, putt well, etc.
For Gary, it was a “perfect storm”: calm demeanor and thoughtful execution. He didn’t change his style. Gary confidently maintained and owned his way to play. He excelled at the right time in the perfect place.

Most golfers could benefit from Gary’s mental approach when they play golf. Stay in your lane, do the things you can, keep it simple, etc. All good advice. Those who understand and can apply these simple thoughts to their own game will experience more enjoyment and more success. For the others, hopefully, they can find a PGA Professional to guide them there.
