Your great-grandkids won’t know your username. They might know you fixed things, told jokes, and always brought dessert.

What gets passed down is a short list of habits. Accounts, scores and handles disappear with the platforms that hosted them, and what survives three generations is the kind of thing somebody could say in one sentence at a dinner table: he fixed things, she was funny, they always brought dessert. The summary is tiny, and it is almost always about what you did for people.

Ask which three habits you would want on that list, then check whether you actually do them. Pick the one you are furthest from and do it once this week. Being known for bringing dessert requires bringing dessert.
