Advice to my kids: the internet makes the world feel very small, while in reality it is very big.
People can say anything they want on the internet, and it is amplified by the algorithms that push it at us to maximize engagement and consumption (because advertising). This means you will get hot takes put in your face frequently, and it will be targeted specifically to get a reaction from you.
The great part about the internet is that you have a close button. Go outside, touch grass, and enjoy some sunshine.
