Somebody worked double shifts so your last name could walk into rooms theirs never saw.

Doors that open easily for you were often forced open a generation or two back, and the cost was paid in hours nobody thanked anyone for. You did not ask for that and you cannot repay it directly. What you can do is know about it, because access that feels ordinary to you was built by someone who found it anything but.

Find out what the people before you actually did for work and what it took out of them. Let that sit beside your own account of a hard week. Then use the room you get to walk into for something they would recognize as worth it.
