You can't the mind that refuses to change.
"Against stupidity, the gods themselves, contend in vain." Friedrich Schiller
Or, 'You can lead a horse to water, but you can't make him drink.'
Don't waste time with the people who refuse to listen; work on building a network of like minded people.
What can someone who lives in an apartment building do? Or a student in a dorm? Which candidates should we support.
Your time is a limited resource, don't waste it pounding deaf ears.
