Northampton Saints' Tom May says they are putting an end to the mistakes that caused early-season defeats.
The 32-year-old made his 200th Premiership appearance, and scored two tries, in the 44-15 win over former club, Newcastle Falcons.
"We were beating ourselves. Discipline was poor and wasn't great today to be honest," he told BBC Radio Northampton.
"Once this team has confidence, we'll be difficult to stop and hopefully we can continue that."
May joined the Saints from Toulon in the summer, having spent 11 seasons with the Falcons.
"It's nice to reach 200 Premiership games against Newcastle, who I started my career with," said May.
"My reaction when I scored the first [try] was probably a bit over the top, and fairly aggressive, but I was desperate to make a mark today, and not just because it was Newcastle.
"I'm head-to-head with James Downey and I have to play well to stay in the team. We're lucky as a squad - we have two or three players in every position that can come in and do a fantastic job."
May enjoyed a good first season in the south of France, with Toulon reaching the Top 14 semi-finals and Amlin Challenge Cup Final, but the centre admits he is happy to be back playing Premiership rugby.
"What Jim Mallinder, Dorian West and Paul Grayson do really well is involve everyone and everyone feels valued.
"It was the same at Newcastle when I was there, and slightly different over in France. The first year was fantastic and I loved playing for Toulon.
"The second year was a lot tougher, but it gave me a better perspective on life and rugby.
"[At Saints], I'm loving the club, the fans and the squad I'm with."
