I have come across the following quotes and thought some of them interesting:
"Considering the amount of stupidity out there it is amazing that humanity has come so far"
"Understanding reality is overrated"
"I will make the world a better place or die trying"
"He battled with stupidity and lived to tell about it"
"Dealing with stupidity on a daily basis, can leave you psychologically damaged if not completely insane"
"A man can meet his destiny on the road he took to avoid it"
"You can't outsmart stupidity"
"Reality is even worse than you think"
