The "lucky 10,000" mindset (https://xkcd.com/1053/) is a much more positive and helpful way of thinking about things than the "how do you not know that?" mindset. try to make people part of today's lucky 10,000, not just belittle them for not knowing things!

it always confused me when someone bettering themselves was seen as a reason to make them feel bad
