What does quiet confidence mean?

It's a quiet assurance that you can handle whatever comes your way. It comes from self-awareness and knowing that your intrinsic value isn't based on your external circumstances. You don't need to put others down to feel good about yourself.

Well I can tell you it’s NOT when people scream for attention and validation on this site. LOL

But seriously peeps have left good answers!

Not cocky… someone who is sure of themselves and feels no need to prove it to those around them.

You're confident but have no need to brag about it?

Being self assured and competent in behavior and action, without self promotion/bragging or seeking validation.

Confident but not arrogant

Stay put with folded arms. When you hear yer name to do the task ONLY then... unleash your knowledge and power in completing the task.

You live it, don't talk it. No arrogance and looking for attention
