Gloucestershire captain Alex Gidman says their four consecutive FL t20 defeats have 'gone from the memory'.
Gidman's side moved off the bottom of the South table after beating Surrey by 46 runs to claim their first victory in this season's campaign.
"In a way the four losses have already gone from the memory," Gidman told BBC Radio Gloucestershire.
"It's now about gathering as many points as we can to give ourselves a chance in the competition."
He continued: "It's crucial that we sit back and realise what we've done exceptionally well in this game and obviously try and repeat that as much as possible."
"We are fortunate this year with how long the competition is as we've proved to everyone how good we can be," he said.
"It's a monster competition and to get to the quarter-finals you don't have to win the group, you have to be in the top four, and there's a huge amount of cricket left.
"We are a third of the way through, if we go on a roll we can give ourselves a good chance."
