"Those who think they know EVERYthing
annoy those of us who do."
What would make this grown man put this handwritten sign on his shirt like this?
It's funny some people really do think they know everything.
And they are the hardest and most annoying people to listen to, because their pompous arrogance blinds them to what others think, feel, and have to say.
The only way to really know many different things is to learn from others and then incorporate that into your brain matter.
Progress (societal and self), including thinking, is incremental--that's why education is so important!
No one (except G-d, of course) knows everything, but everyone knows something.
So we can learn from everyone!
Don't fear other's people knowledge, skills, and abilities--we are a community and we really only work well when we function together.
It's like on most of the survival shows I've seen--one or two people (even those highly trained) fail miserably at long- (or short-) term surviving, because "it takes a village!"
Overall, I like my father's humble version on life much better:
