"I don't get into that second guessing of myself publicly"

In this quote, previous Canadian Prime Minister Stephen Harper is expressing his unwillingness to publicly question or question his own choices. He is stating that he does not take part in the act of second-guessing himself in a public online forum. This might be analyzed as an indication of self-confidence in his own abilities and choices, along with a desire to keep a strong and undeviating image to the general public. It could also recommend that he prefers to keep any doubts or unpredictabilities about his options personal, instead of airing them out for others to inspect. Overall, this quote reflects Harper's approach to management and decision-making.
