And the Canaries have now claimed points in the dying minutes in each of their last three home games.
"We're fit and strong, but we've got a team that wants to score goals, we play with a tempo and a purpose - we want to win games," he told BBC Radio Norfolk.
"You saw last week against Burnley, we never go to away grounds and sit-in, too many draws are no good, you need to win games," he added.
City had similar comebacks against Cardiff and Millwall, with Russell Martin scoring a 90th minute goal to earn a draw against the Welsh side and Henri Lansbury netting a last-kick winner against the Lions.
Holt's dramatic winner against Reading sealed a move that begun when chief executive David McNally hastily threw a loose ball back from the director's box for a Norwich throw-in.
Holt says it showed that the urgency for victory goes beyond the first-team squad.
"It's passion, you can see that from Michael Foulger [deputy chairman] putting
his ?2m in this week,
as well as Delia [Smith] and how long they've supported the club.
"When you see that you can see the passion is from top-to-bottom, we've got a squad and a board who want to achieve things."
