Millwall now have three home games on the spin and Harris thinks its the perfect launch pad for the team to finally get their season going.
"We were disappointed with what happened at Oldham," Harris told the club's official website. "But Southend are always a good team and Northampton away is always a tough one.
"We've got two points on the board and we must be positive - that is something to build on. We can make sure that the draw we got at Northampton was a good point by following it up with a win at home.
"Hudersfield is the most important game to me simply because it is the next one. After hopefully beating them, we have got Colchester and obviously the big carrot in the JPT is that the Final is played at Wembley. If we can win those two and then follow up with a good result against Hartlepool a week on Saturday that would push us right up the table."
