John Coventry’s team came out on top in a classic Essex derby, 5-3 winners over the Iron.
Quinton says the loss won’t provoke a backlash from him – and that he accepts it was a bad day at the office.
The new manager knows his players’ lack of years may have contributed to Tuesday’s result but you won’t finds him over-reacting.
Braintree return to Cressing Road this weekend and play Hampton and Richmond Borough.
The Iron manager wants a response from his side and the start to life in the Vanarama National League South is what he expected.
“We knew there would be ups and downs,” said Quinton, who returned to the club this summer after ending his time in charge of Enfield Town.
“It’s important to remember we are a young side and young sides are going to have off days, it’s a natural part of life.
“We’ll learn from it, I think we will actually take lessons from the East Thurrock result and hopefully on Saturday when we play Hampton we will show it was just a bump in the road.”
Braintree had previously beaten Eastbourne and Chippenham and claimed a draw at home to Dartford.
“Seven points is not the worst return in the world so I’m not concerned,” the manager said.
