Ryan Jones has warned Wales "not to rest on their laurels" after their opening Six Nations win over Ireland.
The double Grand Slam winner has also told his Welsh team-mates to forget about winning Championships as they prepare for Sunday's visit of Scotland.
"We're a bit early to talk about Grand Slams, we're only one game in," said the experienced Ospreys forward.
"It is not about resting on your laurels, it is about building on the confidence we've gained from this."
Jones is one of the most experienced players in the Wales squad and the former skipper, who captained his country 27 times, was back to his impressive best at blind-side flanker in Wales' thrilling 23-21 victory in Dublin.
But Jones, inspirational in Wales' 2005 and 2008 Grand Slam winning campaigns, insists Wales should not be celebrating too much after their first win since ending Ireland's World Cup dream in October.
The 30-year-old, who won his 59th international cap in Dublin on Sunday, excelled as he replaced World Cup blind-side Dan Lydiate, missing with ankle trouble, but reminded his young team-mates to keep focused.
"It was by no means a complete performance," insisted Jones.
"There will be lots of finger pointing and we'll tear apart the game, looking at areas of concerns and weakness we perceive that we have and build on them.
"We have to take the positives but there are some lineout issues we have to iron out, we'd like a bit more from our scrum, we have to work on our breakdown and we have to look at our ball retention.
"We're always looking to improve - and it is a competition where the team will develop as it goes on.
"It was the start we so dearly needed and it bodes well."
Rhys Priestland missed three kicks - a conversion and two penalties - and Wales, who spent ten minutes with 14 men after lock Bradley Davies' yellow card, fought back to win in the last minute thanks to Leigh Halfpenny's penalty.
"We dug deep when Brad went off," said Jones.
"That was the spirit we showed in the World Cup and we've managed to carry that on and have come away with a wonderful result.
"Grand Slams do start with a victory, I suppose, and we are in control of our own destiny."
