Henrik Stenson said "the little perfectionist" inside him will not allow the new Open champion to rest on his laurels as he targets further success at the US PGA Championship this week.
Stenson finally won a first major title which had proved to be so elusive when he lifted the Claret Jug at Royal Troon less than a fortnight ago after finishing an Open-record 20 under par.
The Swede was showered with praise following his remarkable performance in tough conditions on the South Ayrshire coast, where he and Phil Mickelson put on a remarkable exhibition under pressure.
World number five Stenson is still eager to raise his game as he prepares to tee off at Baltusrol on Thursday.
He said: "I think golf is a game you're never going to be finished. You're never going to get to the point where you're maxed out in your ability and how you're playing, so there's always that strive to become better.
"I've got a little perfectionist in there that's always been pushing me forward and that can both make me and break me at times, when you're striving to be your best.
"But I don't think I'm going to sit back and just say, 'Okay, that was it, I'm finished.' It's definitely the icing on the cake. If I look at my career, to win a major championship, that was pretty much the only thing I had not managed to achieve and now I have that.
"But then at the same time, you can look ahead and then try and win another one.
"So I think I've still got a good few years in me and I'm going to try and keep on developing, and if you don't, these young guys are going to come up and take over. So I still think I've got a bit of fight in me."
Stenson will play his first two rounds at the US PGA with Dustin Johnson and Danny Willett, the other two major-winners this year, in Springfield, New Jersey. The trio tee off at 1.45pm local time on Thursday
