Ryan Jones warned against complacency following Wales' thrilling last-minute victory over Ireland in Dublin on Sunday.
Jones and company arrived home from Dublin on Monday after putting themselves on course for silverware with a 23-21 win at Lansdowne Road.
But the flanker says this season's competition remains wide open and believes that next Sunday's clash with Scotland will be no walk in the park.
"It was nice to be on the right end of a result like that," said Jones, who took over the captaincy after Sam Warburton departed with a leg injury at half time.
"A lot is made out of the importance of confidence in this competition and it helps when you start with a win.
"We are buoyed by the success, but next weekend is another game and Scotland will be smarting after losing to England in their first match.
"We know what challenge they are going to bring early doors, so it is up to us to get our own house in order.
"We have to keep winning. You can talk about confidence and momentum, but this competition is about one game at a time. It is still wide open.
"But we have put ourselves in a good position. We are still in control of our own future, which is where you want to be going into the next few fixtures.
"It was wonderful to be in that changing room and nice to be on the end of a result like that for a change. We seem to have been on what I would call the wrong end a few times.
"It was a great afternoon, a wonderful advert for Six Nations rugby with two teams going at it hammer and tongs and the game won in the last 20 seconds. The drama was wonderful."
Jones also saluted some high-class individual contributions, notably from try-scorers George North and Jonathan Davies, scrum-half Mike Phillips and prop Rhys Gill, on his first Six Nations start.
"I thought George was great," he added. "He did everything asked of him and a bit more.
"At this level it is nice to have something up your sleeve like George, and he came up with a wonderful bit of skill to put 'Foxy' (Jonathan Davies) in for his second try.
"He and George were wonderful individuals, while Mike Phillips and Rhys were superb. It bodes well.
"A lot was made of the injuries, but everyone stepped up to the mark and performed. The boys deserve all the credit they get."
