Usain Bolt's career is a disappointment to nobody — except, perhaps, to Bolt himself.
Speaking from the IAAF awards after winning male Athlete of the Year, Bolt said if he could go back in time, he would change one thing: taking his sport more seriously early in his career to have won more medals.
"I was relying more on my talent. If I'd got more serious I think I would have done a lot more in my career. It's shocking but it's true. Maybe if I'd started younger I'd have had four Olympics."
Bolt said that after losing to US sprinter Tyson Gay at the 2007 World Championships, his trainer motivated him to get better.

Usain Bolt of Jamaica turns to look at Andre De Grasse of Canada as they compete in the Men's 100m Semifinals at the 2016 Rio Olympics in Brazil, August 14, 2016. Kai Pfaffenbach: 'When Usain Bolt prepared for his 100m semi-final I decided to play with slow shutter speed for that race. I set my camera (shutter speed) to a 50th of a second and was waiting for the moment when he passed my position. At the very right moment he looked to his left with the proud smile and my first thought was: "hopefully I got this sharp." Well, I've been a lucky bunny in this case but I still would not have imagined at this moment that this picture would go viral and get worldwide recognition.'

"After I lost I remember going to my coach saying, 'I really tried my best but what can I do to win because I really need to win?' He said, 'You're slacking off in the gym. If you want to win you have to get stronger.' So I was like 'alright'. I knew what I needed to do and from then I took the step and just worked and worked."
Bolt is largely considered the greatest sprinter of all time. He completed a triple-triple in the Rio Olympics this year, winning gold medals in the 100-, 200-meter, and 4x100-meter in for the third time in his career, to bring his gold medal total to nine.
Bolt added that he is reducing his workload for one more season in which he'll only run the 100-meter.
Bolt didn't disappoint in dominating three Olympic games, and he went out on top, but what he could have been if he took his sport more seriously is a tantalizing thought.
