There seems to be a mental shift that happens around 30-50 (depending on the person) where the mindset changes from "How can I learn and contribute to world?" to "How can I make the world work the way I want?" and it's very noticeable in the public speaking engagements these people do, as this mindset seems to blend with all their other thoughts and feelings.

Luckily, this doesn't seem to happen to everyone, especially if you aren't a public figure, a billionaire nor a successful startup founder, but that particular combination seems to make it extra likely you experience this transformation.
