Harbin said: "This could be my only game in charge and it was a privilege. If it is not just this game then maybe it will only be two matches.
"I might only be manager of a football team for one game, so I wanted to enjoy the moment and that is what I did.
"I aged five years but I enjoyed it. The clock goes a lot slower when you are down in the technical area as opposed to being in the stands."
Harbin felt the draw at the Ricoh Arena was a fair reflection of the game.
"I am happy with the result and I think it was about right," said the Australian.
"Cardiff are a very good team, one of our scouts said they were one of the best teams he had seen in this league, so I am very pleased."
Harbin, a fitness coach by trade, was particularly pleased with Coventry's effort.
He said: "We showed a lot of spirit and that got us through the game.
"There was a lot of effort and the work rate was good. We had to hold out a bit in the second half but the endeavour was there."
Dave Jones was left disappointed that City were not able to win the game.
"We had numerous chances to put it to bed after the break and we didn't," said Jones. "I am disappointed with that.
"The first half was a scrap and a battle and we never really got going.
"But in the second half we have come out and created some good chances so we are frustrated because we should have really won it."
