One page a day is a book in a year. Nobody writes a book in a weekend.

Big things are almost never built in a burst, they are built by a small amount repeated past the point where it feels impressive. A page is nothing on a Tuesday. Three hundred of them is a book, and there is no shortcut where you skip to the total. The weekend sprint people imagine does not exist.

Choose the unit you can do on your worst day and make that the rule, not your best day. Keep it small enough to survive a late shift or a bad mood. What you are protecting is the chain, not the size of any link.
