Stuart Broad said his hat-trick against India will mean little if England do not go on and win the second Test at Trent Bridge.
Broad dismissed Mahendra Dhoni, Harbhajan Singh and Praveen Kumar, but England still trail by 43 runs.
"Your best days only come when you win, so at the end of the Test match it might well turn out to be if we perform well," Broad told BBC Sport.
"It was a pretty special occasion, but it's all about winning Test matches."
Going into day three of the Test, Broad added: "Sunday's a huge day of cricket, it's all about winning games and I expect the crowd of Nottingham to be pretty similar and supportive."
Broad becomes the 12th Englishman to take a hat-trick in Test cricket and the first since Ryan Sidebottom in Hamilton in 2008, as well the first player from any nation to capture a Test hat-trick against India.
Asked about his feelings ahead of the hat-trick ball, Broad added: "The atmosphere was amazing, Trent Bridge was really bouncing.
"I wanted to take a little bit of it in, of course, but I knew that it was a good chance to knock over the tail.
"The ball was moving a little bit and I wanted to make sure I hit the stumps, so I just came wide of the crease and tried to angle it in as close to the stumps as I possibly could, and fortunately it just nipped back and caught the top of off [stump]."
And speaking on BBC Radio 5 live's Sportsweek, Broad's father Chris - match referee at the Test - spoke of his pride.
"It's strange this game of cricket," he said.
"One delivery can change momentum. Clearly Stuart found line and length at Lord's and has confidence now, he's bowled a great line at both Tests [the bowler taking seven wickets in the first Test of the series].
"For the hat-trick ball we were all on the balcony, all dreaming of the possibility he could do it but never believing as there are so many times you get two wickets in two balls.
"Afterwards, I probably pushed my role as match referee too far. I went to the England dressing room and gave him a big hug. I had to go up and say well done at that moment."
England's hopes of taking full advantage of the platform provided by Broad could be dealt a blow if Jonathan Trott is unable to bat in the second innings after injuring his left shoulder when he dived to stop a Rahul Dravid cover drive.
Trott immediately looked in pain as he writhed on the outfield but an X-ray later showed no bone damage to the shoulder and he could be pressed into action on day three.
"He's in a little bit of pain this evening but we're hoping, with no major structural damage, it will pull up a bit better in the morning and he might be able to play some part with the bat," Stuart Broad told Test Match Special.
Ian Bell batted in Trott's number three position after England lost Alastair Cook early in their second innings, and they will go into day three with a deficit of 43 runs and a wicket down.
The situation would have been considerably worse had it not been for Broad's heroics with the ball.
Playing on his home ground, Broad took five wickets - including the hat-trick - in 16 balls to haul England back into the match after India led by 46 on 267-4.
"We dragged ourselves back into this game," said Broad. "It was a tough day for the bowlers to be honest, I thought the wicket slowed down - the heavy roller certainly had an effect this morning.
"To only be 43 behind this evening, we're in a strong position to really build on. When they passed our score with only four down we were staring down the barrel a little bit."
England did have an opportunity to limit India even further but Kevin Pietersen dropped Yuvraj on four, and he went on to make 62.
"No-one means to drop catches, KP was frustrated with himself," said Broad. "These sort of things happen in cricket but it was looking like it was going to hurt ourselves for a little while.
"Fortunately we managed to wrap up the tail pretty quickly. Unfortunately we lost Cookie, but if we get clear skies we'll be looking to get a big total."
