I often hear people referring to themselves as "strong" or "assertive" or "confident" or "honest",
when in reality, they are actually arrogant, obnoxious, and rude... there is a huge difference.
"There's a fine line between confidence and arrogance. This is especially true given both entail a strong belief in one's own abilities. When it comes to the responses they provoke, however, that's where the similarities end.
Confidence is inspiring; arrogance is a turn-off. Confidence gets hired; arrogance is shown the door. Building confidence takes work; arrogance is simple. In fact, it's easy to come off as arrogant." -The Ladders
