The Gunners boss has found his position under intense scrutiny, after a midweek 3-1 defeat in the Champions League by Bayern Munich followed on from their shock FA Cup exit at home to Blackburn and Capital One Cup loss to Bradford.
The 63-year-old - whose side are set for an eighth season without silverware - reacted angrily earlier this week to "lies" the club had already opened talks over a new deal, with his current contract set to expire in 2014.
However, despite the negativity surrounding his squad, Wenger says he is not about to walk away from the challenges ahead - insisting his desire for the job burns as bright as ever.
Asked directly if he had considered his position this week, Wenger replied: "Never. Not one second.
"I don't think that (motivation) spark has anything to do with the length of your life. It is just that's how you are and you're motivated by how much you want to win and how much you are a winner.
"If I go out now and play one against one with you, you will see I will beat you and at least if I don't manage to beat you, I will want to beat you. That will not change as long as I can move."
Wenger believes there needs to be a sense of "perspective" around achievements at the Emirates Stadium, with Arsenal having continued to qualify for the Champions League despite testing financial circumstances.
"We live in a world of emotion, of excess, and it is down to people who have responsibilities to put that into perspective and keep solid and keep guiding the club in the right way," said Wenger.
"My responsibility is to keep the guidelines and guide the team and the club in what I feel is the right way. What is important for me is to focus on the next game and try to give my best, like all the players."
