Rory McIlroy won his second FedEx Cup title in August
Rory McIlroy says he would not feel a "hint of disappointment" about his season if he were a different golfer.
The Northern Irish won four titles in 2019, but failed to cut his home Open Championship at Royal Portrush or take on a challenge with one of the other majors.
"I am almost a victim of my own success," said the 30-year-old.
"What I could do at the start of my career, by winning four majors by the age of 25, is not really the norm."
He added: " If I was another golfer who did what I did this year, I don't think there was a hint of disappointment.
"I feel that I am still young in terms of being a golfer and I have a good 10 or 15 years for me, but it's hard to go through interviews and feel like you had a great year but there is always a & # 39; but & # 39 ;. "

The last season was five years ago since McIlroy last won a major title, but he still believes he has had a strong campaign and has improved as a player.
The world number two won the Players Championship, Canadian Open, FedEx Cup and WGC-HSBC Champions and was the PGA Tour & # 39; s player of the year.
"I have played some of my best golf and I have also been more consistent. The four wins there were fantastic," he added.
"If someone had told me on January 1, 2019 that I would have this kind of year, I would probably have taken it.
" I feel that every aspect of my game has this year has improved, and if I can keep improving those little things, then there is no reason why I can't do that successfully.
"I have had a good year, and I am happy with where my golf and my life are, and I think I will be even better with that next year. Second in the world ranking.
Koepka, a four-fold big winner, has been number one since 2018, but McIlroy says he is determined to win back the first place, regardless of who leads the way.
"It's on the radar and certainly a purpose of me next year, "admitted McIlroy.
" I want to go to world number one, I don't care who occupies it.
"I started the eighth year in the world and made it number two, and I know for sure that I will get the chance to get there early next year."

McIlroy admits that he is worried that he has not won a major since he won a PGA Championship and Open Championship double in 2014 did, but says he knows he has the quality to add to his count.
"There are other things that are important to me, except for major championships, and there are many things in golf that I play for that are not four weeks a year," he said.
"You only have a limited number of opportunities per year and sometimes it just doesn't go like you.
" I & # 39; play good enough golf at tournaments at other times of the year against some of the best players in the world, so there's no reason why I can't do it during those four weeks either.
"Competition will always be there and new people will always come through.
" But if I can use all my experience and learn from all the opportunities I have had over the past 10 years, then I would be very disappointed if my next 10 years were not even better. "
