O'Sullivan was voted Player of the Year at snooker's annual awards ceremony at the end of the 2013/14 season having won four titles during the campaign, though he finished it with his first defeat in a Crucible final.
The Rocket's first trophy of the season came at the Paul Hunter Classic European Tour event in Germany when he beat Gerard Greene 4-0 in the final. He then won the new Champion of Champions event with a 10-8 victory over Stuart Bingham.
At the Masters, O'Sullivan's snooker was spell-binding, particularly in a 6-0 quarter-final drubbing of Ricky Walden in which he scored a record 556 unanswered points. He went on to beat Mark Selby 10-4 in the final to win the title for the fifth time.
And at the Welsh Open there were more fireworks from the sport's most talented star. He conceded just ten frames in seven matches and beat Ding Junhui 9-3 in the final, finishing in perfect style with a 147 break. That was the 12th maximum of his career, edging him one ahead of Stephen Hendry.
"It's a nice record, to have 12 maximums," said O'Sullivan after winning the 26th ranking title of his career. "I suppose a little bit of me wanted to take one of Hendry's records. I am happy I have won and have had a good week. It is just about getting the CV looking as nice as you possibly can. The enjoyment is in the doing so I am glad the tournament is over now. I am trying to get the balance with enjoying home life and snooker."
On to the World Championship and O'Sullivan was targeting his third title in a row and sixth in all. He came from 11-9 down to beat Joe Perry 13-11 in the last 16, then saw off Shaun Murphy and Barry Hawkins - both with a session to spare - to set up a final meeting with Selby. O'Sullivan looked in control at 10-5, but lost his rhythm against the grittiest of opponents and eventually went down 18-14.
"As a top snooker player you accept the losses with the wins, you can't have it your own way all the time. I've had some great victories here but losing is part of the sport and you've just got to accept that," he said.
O'Sullivan won the world crown in 2013 despite taking virtually a whole year away from competitive snooker. He beat Barry Hawkins 18-12 with six centuries in the final. That made him the first player since Hendry to retain the title, having beaten Ali Carter 18-11 in the 2012 final.
O'Sullivan first won the world title in 2001 when he beat John Higgins 18-14, his second came in 2004 when he easily saw off Graeme Dott 18-8 and his third in 2008 with an 18-8 defeat of Ali Carter.
O'Sullivan's fast, attacking style and charismatic personality have made him snooker's most popular player across the globe.
Blessed with the rare gift of being able to play to a high standard both left-handed and right-handed, he made the fastest 147 on record at the 1997 World Championship, a blur of potting which lasted 5 minutes and 20 seconds.
In a match against Carter at the 2007 Northern Ireland Trophy, O'Sullivan became the first player ever to make five centuries (including a 147) in a ranking event best-of-nine match, winning the game 5-2.
Away from snooker, he is dedicated to long distance running, a pastime which he believes has helped him enormously in his battle against depression.
He counts artist Damien Hirst among his closest friends, and also credits the renowned psychiatrist Dr Steve Peters as playing a key role in his recent success.
O'Sullivan has a daughter called Lily, born in February 2006, and a son called Ronnie born in June 2007.
