The chair you’re in, the road you took, the app you’re using: all built by people you’ll never thank. Pass it on.

Almost everything around you was made by strangers solving problems you never had to think about. Somebody engineered the thing you are sitting on, somebody paved the route, somebody stayed late fixing what you are reading this on. None of them will ever know your name, and the whole arrangement only works because people keep doing useful things for people they will never meet.

Since you cannot repay upward, the only available move is sideways. Do something useful for somebody who will not know it was you. Leave the room better, fix the broken thing, write the notes that help the next person.
