I never liked anyone who didn’t have a temper. If you don’t have any temper, you don’t have any passion.

Bloomberg draws a sharp distinction between mere irritability and the deeper energy that drives people to care, argue, and act. In his framing, a “temper” signals emotional investment—someone who reacts strongly because something matters—whereas the absence of temper suggests detachment or complacency. The quote also implies a leadership or workplace preference: he values intensity, urgency, and conviction, even when it produces friction, over cool neutrality. At the same time, it invites a cautionary reading: passion can motivate excellence and reform, but unmanaged temper can become volatility or intimidation. The line therefore functions as both a defense of intensity and an implicit challenge to channel it productively.
