Martin Kaymer returns to Sun City at the end of what has been a frustrating year for the German. But it has also been a year that has reinforced the unshakable optimism that has become a hallmark of his career.
Twice in 2015 Kaymer let slip golden opportunities to win on the European Tour. In January he led the Abu Dhabi HSBC Golf Champions by 10 shots with 13 holes to play. Then he quite inexplicably shot a closing 75 to finish third. It was a defeat that shocked Kaymer, but one which he turned into a positive. His reaction to one of the great collapses in the history of golf spoke volumes for the kind of perspective Kaymer brings to the game and his own career.
"It was more important for the future to lose, in order to win more. I don't want to call it a bad experience because it is not a bad experience. It creates a bad result on your scorecard but also reveals a lot of truth about yourself. That we are not machines, that the German engineering doesn't always work. It does work, usually, but once in a while it sticks, too.
"If I had won again ... That would have been good, but I wouldn't have gained much. I would have got a little more money, a few more world ranking points and a beautiful trophy for my house. Instead, I lost a few world ranking points, a trophy and some money. But I can handle all three of these things. It was almost like a life lesson, not only a golf lesson, that I got there. So therefore, I am very glad that it happened."
Then in the Open D'Italia in September, Kaymer lost a three-shot lead and an eventual playoff.
It was another blow in a season where he also lost his playing privileges on the PGA Tour for 2016.
But again, Kaymer has chosen to focus on the positives.
"A positive thing is I can be home more," he said. "I don't need to worry too much, going to America and going back, all of that back and forth. It's less I need to worry about."
This kind of composure in the face of pressure and the challenges of life and golf is what has made Kaymer such a valuable asset in the European Ryder Cup set-up, and which is also reflected in the three winning teams he has been on. None more so than in 2012, when he holed what some might consider the most pressure-filled putt a golfer can face - the one to win his team the Ryder Cup.
Kaymer still refers to his eight-foot putt to seal victory for Europe at Medinah as a gift. "I was given the opportunity to make one of the most pressure filled and memorable putts in the history of our sport. There will never ever be a more important putt in my life."
Kaymer's mental fortitude is incredible for a 30-year-old. And his ability to take his experiences and learn from them is what sets him apart.
When speaking about the slumps some of the top European players go through - including himself - in between Ryder Cups, Kaymer brings his own perspective to this.
"I think it's quite normal. Some players need a lot of time to reflect and really think about what happened and to enjoy the experience of the Ryder Cup."
And in looking at the phenomenal rise of Jordan Spieth, Kaymer speaks from his own experience of struggling to deal with the pressure of becoming world number one in 2011.
"It all comes down to how he can handle the whole situation outside of golf. We don't know how much it can change someone if all of this comes to you when you are 22 years old."
Kaymer is a man who thinks deeply about life and golf, and it reflects his own approach to the peaks and troughs that are part of a golfer's career.
"We all need to give both others and ourselves a bit more space. In today's society we judge everything far too quickly. There is this saying, 'form is temporary, class is permanent'. I would rather subscribe to that idea."
He returns to Sun City as a double Major champion hoping to add a second victory in the Nedbank Golf Challenge to his impressive CV.
In 2012 he beat Charl Schwartzel at the Gary Player Country Club to secure a German double that year, with Bernhard Langer winning the Champions Challenge.
To paraphrase Kaymer, that was a week when there was certainly zero defect in the German engineering.
