"I'm obviously feeling good so it was great to get a goal," said Earnshaw.
"I'm very pleased for me and the team."
Earnie secured Cardiff's win over Doncaster when he scored from six yards out (right) to put City 2 goals up. It was far from a classic but the result was all important as City dug deep and took all three points. He's now scored three goals in six League games.
"It's what I'm here for," Earnshaw said after celebrating his 201st league goal.
"I want as many chances as possible. It was a good day to score and we needed it.
"We wanted to start sharp, we wanted to set the tempo, we want to be on the front foot, we want to put teams back and want them to fear us.
"It sets the standards. I think we're a good team if we do that and that's what we try and do more often than not."
