ED Upson had mixed feelings after scoring his first Millwall goal on Saturday.
The midfielder's 41st-minute strike ultimately counted for nothing as the Lions slipped to a 2-1 defeat to Huddersfield Town.
But Upson believes Millwall cannot afford to feel sorry for themselves with a game against Birmingham City's coming up tomorrow – and has set his sights on more goals.
"I'm really pleased to get my first goal and break my duck but obviously I wish it had meant something in the game," he said.
"I'd just hit the underside of the bar so I was starting to think that it was never going to go in for me. Scott McDonald crossed the ball in and I gambled with a run into the box.
"I like to have a shot and get in the box so hopefully I can get a few more.
"We have to stick together and be positive because we've got a job to do on Tuesday.
"There will be ups and downs throughout every season and how you deal with those will determine where you end up in the league.
"The manager was very honest and we know that we have to improve on that performance. He'll get us going again, that's for sure."
Having got themselves back on level terms, the Lions offered little in the second half and Nahki Wells' penalty decided matters.
"It's tough staight after a game to put your finger on what went wrong," Upson added.
"It's very disappointing to come here and put in a performance like that because it is a long way to come. We have to react on Tuesday and look forward.
"None of us turned up here to put in a flat performance or not put the tempo in. It's just a shame. We've all got to look at ourselves and analyse it.
"We've got to kick on because there's another game tomorrow and we can't let it get to us.
"Thankfully we don't have a whole week to stew over that performance. If we put it right against Birmingham, it all looks good again."
