The Demons take on Essendon at Docklands on the big stage of Friday night football this week where their actions and not their words will do the talking according to Sylvia.
"We had a couple of good group sessions just with the players to reassess where everyone's at and to look everyone in the eye and get some opinions," Sylvia said from Junction Oval on Wednesday.
"We're sick and tired of getting an honourable mention for performing okay and giving a good effort. Football is about winning, so we've just got to stick to the process now and hopefully get some runs on the board.
"We have a strong belief that we're going to get some wins on the board in the second half of the season. If it was three or five wins it would be fantastic for us as a group and also the supporters.
"We're really excited to play this Friday night. We know it's a winnable game for us. If we bring the right mindset and stick to our game plan then we've definitely got the belief in the group that we can win the game."
Melbourne reached the midway point of the season on the bottom of the ladder with just one win.
Sylvia admitted the club's position was unsatisfactory and frustrating given the progress he feels has been made.
"This is our third year in a row now that we've been pretty disappointing, but I suppose this year we can see the light at the end of the tunnel and see the clear direction the club's going in," he said.
"We've come such a long way, as opposed to this time last year, and we really took a backward step last week [against Collingwood].
"We just didn't bring the right attitude to that game and we need to this week. We need to respond and show some real character and show the footy world where we're at."
Sylvia's form has been one of the positives of the Demons' season to date with the 23-year-old's body finally allowing him to compete at the highest level after a long and painful battle with osteitis pubis.
"I've come along a little bit this year, but there's still a long way for me to go; I'm not out of the woods yet," he said.
"My main focus is the second half of the season and to continue to be measured for my actions from here on.
"It's been a bit of a rollercoaster ride with injuries, but I'm just confident in my preparation now. I'm getting myself up each week for each game, I'm not missing training like I have in the past and I've completed my first full pre-season.
"It just goes to show how much behind the eight ball you are if you don't get a good pre-season under your belt."
