David Wheater wants Bolton to build on Tuesday's 2-1 win at Aston Villa as they battle to avoid relegation.
The victory moved Bolton, who still have a game in hand on all of their rivals, to within a point of safety.
Wheater told BBC Radio Manchester: "It gives us a fantastic start going into the last four games of the season.
"The players have never lost once confident because we can play better than we have been. The second half against Villa showed what we can do."
Owen Coyle's side have home games against Tottenham and West Bromwich Albion and trips to Sunderland and Stoke remaining.
"We need to go out hoping we can play to our maximum in every game," added Wheater. "If we can do that, we'll be alright.
"We don't see why we can't win all of them. They're all going to be tough games, especially the Spurs game because they're a top team, but we just need to be confident."
Meanwhile, midfielder Chris Eagles has praised the impact that club captain Kevin Davies had as a half-time substitute in the victory at Villa Park.
"It changed the game," said the former Burnley man. "He's so strong, he's got so much experience and power, it's scary.
"It was a massive win. It didn't matter how it came, we just needed three points.
"When they went 1-0 up, my heart dropped a bit, but we showed our character and the talent we've got in the team."
