Over time, I have come to believe that knowing when to say I don’t know is one of the clearest signs of genuine competence rather than weakness. I don’t know, but I know who might. I don’t know enough about this to advise. That sits outside my area of expertise. Those are not admissions of failure. They are declarations of discipline, personal honesty, and respect for consequences. There is wisdom in recognising boundaries, particularly when others may assume your previous competence in unrelated matters somehow entitles you to certainty everywhere else.
