The Wolves have won the cup in three of the last four seasons, but have struggled to make an impact in the end of season play-offs, and were soundly beaten by St Helens last weekend.
They get another chance against Hull this weekend, having finished second in the league table, where a win will put them within 80 minutes of a first Grand Final appearance.
Higham said: “We’ve worked hard all year to get a top two position. We stayed around there all year having been consistent and obviously the advantage now is we get that second chance. It’s probably come at a good time as we’ve had that kick up the backside we needed and there are no second chances now.
“We are pretty good at knock-out rugby, you just need to look at our Challenge Cup style with three wins from four, we do know how to win those big one-off games, we need to use a bit of that mentality going into what will hopefully be another three games.
“We just need to have confidence in our own ability. The only pressure we feel is that which we put on ourselves as we don’t take much notice of what other people say. Our pressure is just that we want to challenge for both of the trophies this year.”
Warrington will be looking to add to only two previous play-off victories – over Leeds in 2006 and Huddersfield in 2011 – when they host the Airlie Birds at the Halliwell Jones Stadium on Saturday.
A win will put them in to the semi-finals, where they will face a trip to either Wigan or St Helens.
