Warren Gatland is not getting carried away after seeing Wales beat England at Twickenham in his first game as coach.
Gatland was taking charge of his first game since his appointment
"I was disappointed with the first half, but we re-grouped at half time and hung in there," said the Kiwi.
"As the game went on I think we got stronger and the guys got a bit of self belief and confidence.
"It ended up being a great result for us. We've got a lot of work to do but hopefully we'll get better as this competition goes on."
Wales were 16-6 down at half time in Gatland's first game in charge since his appointment in November.
"I thought we were really poor with too many turn-overs, kicking wasn't great and when we had opportunities to move the ball we didn't," said the 44-year-old New Zealander.
"We were conscious of trying to get something on the scoreboard and to be able to score a couple of tries was the pleasing thing because we could have easily been out of the game at half time.
"I think the guys off the bench - Tom Shanklin and Gethin Jenkins - made a big impact."
Shaun Edwards, Gatland's new defensive assistant, said the denying England a second try, through Paul Sackey, was crucial.

"The defensive set in the last five minutes of the first-half was vital," said the Englishman, whose team had already been hit by Toby Flood's 23rd-minute score.
"They only scored one try and that was from a kick. To concede only one try from a kick at Twickenham is very creditable."
Wales will entertain Scotland in their next match next Saturday, Gatland warned fans against expecting too much too soon.
"It doesn't happen overnight. Physically, we've got a lot of work to do," he said.
"The potential raw material for this team is there. When we do get it right we will be a very good side."
