The 33-year-old’s winner in the 2-1 Ladbrokes Premiership victory over Ross County last week was his fourth in seven games for Killie and his 100th league strike for the Ayrshire club.
Boyd, in his third spell at Rugby Park, also scored 101 league goals as a Rangers player, with seven goals in 18 Scotland appearances.
Ahead of the visit of Partick Thistle on Saturday, where Kilmarnock will leapfrog the Jags into sixth place with a win, Boyd, who made his debut for Killie as a late substitute against Celtic in 2001, said: “It is proving to yourself that you can still do it when you are getting on in years.
“I have never been short of confidence if there are still chances being created, and that has been the story of my career.
“You get written off and there are days when you start to doubt yourself, like at the beginning of the season when I was not really playing.
“When you get yourself in the team and the opportunities are there and you are scoring goals, the buzz is still the same.
“Since I got myself back into the team the goals have come. It is a credit to my team-mates, with the chances they have created..
“As a striker you have to put yourself into the position to score goals and I have done that, but I can’t take all the credit.
“It is probably not until you are finished that you look back to what you have done. Right now it is about how I go and get 101 goals for Kilmarnock in the league and push on from there.
“Saturday gives us an opportunity to do that. It is a massive game, one we look forward to, and we hope we can get the three points.”
