AP McCoy says he has no immediate plan to retire after riding his 4,000th winner, at Towcester on Thursday.
The 18-time champion became the first jump jockey to reach the mark with victory on Mountain Tunes, trained by Jonjo O'Neill and owned by JP McManus.
"As a jump jockey you take it day by day," the Northern Irishman, who turns 40 in May, told BBC Sport.
"I really love what I do, but it is about winning and you need to keep winning. But age is only a number."
McCoy's mark is almost 1,500 more than the next most successful jockey Richard Johnson, who has ridden 2,567 winners.
He had his first winner in March 1992 at Thurles on board Legal Steps for Jim Bolger and is on course for his 19th jockeys' title, but will decide in April whether to go for number 20.
"At the end of each season, I review how I have got on and how I've performed and you make the decision on whether to carry on from that," he said.
"I will look back and ask, 'Did I do OK? Should I still be riding? Am I still riding as well as I have done in the past?' Those are the questions I always ask myself at the end of every season."
McCoy's father said he hopes the 18-time champion jockey will retire at the end of the season.
"I would love him to stop after this year," said Peadar McCoy. "The only thing is he might be tempted in trying to make it 20 titles."
McCoy's younger brother, Colm, said the rider had shown "unbelievable" dedication to his racing career.
"He has given us some of the best days of our lives, but his feet have always been on the ground," he added.
McCoy returns to action on Friday at Southwell, where he will again ride for long-time friends McManus and O'Neill on Forthefunofit in the closing National Hunt Flat race as he chases winner 4,001.
"I'm really proud of what I've achieved and being able to last, one way or another. I'm lucky and proud to have done it," he said.
"You have to have goals. Otherwise you get a bit lazy. I'm one of those people who needs to chase something. I find it easier because I love what I do, but it keeps me working that bit harder."
