The Canaries moved out of the drop zone on Saturday with a 1-0 win over Plymouth - their third win in four games.
However, Bryan Gunn's side could fall back into the bottom three depending on the outcome of Barnsley's game against Crystal Palace on Tuesday, and Crook is adamant he and the coaching staff will continue to hammer home the importance of every game to the players.
"It's a lot better now with the results we've had, but it's still going to be a fight for us," he told the Norwich Evening News.
"If we perform as we have in those three wins and put in that level of performance we should pick up enough points, but we mustn't drop below that level.
"Results are everything when you're talking about team spirit and a positive attitude. Winning three games out of four is the best sort of tonic for team spirit. It makes for a totally different mindset."
