When I was in my 20s I was an insufferable know-it-all who found fault with everything.

I still spot problems and “push back”, but I have the experience now to know how to get people to listen and not just write me off as an annoying prima donna.

Insufferable know-it-alls are easy to steer too. Just look at the DOGE team.
