Humility is strength, not weakness
The strongest people you have ever worked with were almost always the ones least interested in being the strongest person in the room.
An essay by Dustin Michael Drozd
Humility is often confused with passivity. They are not the same thing. The humble professional has firm opinions, defends them clearly, and is also willing to update them when the evidence asks them to.
Ego, by contrast, is a fragile and expensive thing to carry. It costs cognitive room, defends positions long past their usefulness, and pushes away the very people most capable of helping.
On a working team, humility is the bandwidth that makes everything else possible — coaching, feedback, debate, repair.
It is, quietly, one of the most professionally undervalued traits in any field.
