Norris smashed in his eighth of the campaign in the win at Derby on Tuesday and believes he now has the licence to get more under new boss Paul Jewell.
He said: "Against Derby, Grant Leadbitter and Jimmy Bullard allowed me to get forward and I could have had more than one goal.
"I`ve chipped in with goals before but this is the best [tally] of my career.
"It`s something I had to add to my game and I`m delighted with how it`s going."
