I disagree. Introversion at it's core is about sensitivity to over stimulation. This sensitivity to over stimulation is not something that you can control, it's baked into the biology, into the neural connectivity of the brain.

This means that something that is not very stimulating to you, can be practically overwhelming to me.

It's not insecurity, it's not emotional issues. It's biology.

And turning it into something that sensitive people should be able to overcome - turning it into a personal failing is not helpful.
