I mean, knowing when not to talk is a skill, too.

And (supposing we're talking about income or wealth as the metric for success) I'm not saying no given quiet person can be more successful than a talkative person. But all things being equal, the person who is more confident and at ease talking to others and making connections will be more successful.

Also it’s just rude as hell to tell someone you hope your kid doesn’t turn out like them.

I don't disagree
