Seven-times world champion Stephen Hendry has thanked coach and mentor Terry Griffiths for helping him out of the "depths of despair".
Hendry told BBC Sport: "It's almost three years that Terry's been with me.
"When he came to speak to me I was in the depths of despair because my form was rock bottom.
"We worked on a few things and I got my form back. It's fantastic to have someone around who knows what you have to go through in the arena."
Hendry will bid for an eighth world title when the game's biggest tournament gets under way at The Crucible on Saturday.
The Scot dominated snooker in the 1990s, picking up all seven of his world titles during that decade.
He has won a record total of 36 ranking events and amassed almost £8m in prize money.
However, prior to winning the Malta Cup in February, Hendry had gone 18 months without picking up a ranking title.
Now that the 36-year-old has had his confidence restored, he still believes he has what it takes to win an unprecedented eighth world title.
"I'm going to carry on until I know that I'm not good enough to win," he added.
"If you just turn up and know you're not good enough to win then I would find it hard to motivate myself to practice."
