Finishing is a choice you make over and over, especially in the boring middle.

Starts are easy because they come with excitement, and endings are easy because the finish is visible. Between them is a long stretch with neither, where nothing feels like progress and quitting would not even look dramatic. That middle is where almost everything gets abandoned. Finishing is less one act of will than a series of unremarkable decisions to continue.

Make the middle require less of you. Shrink the daily amount, track the count somewhere visible, and tell one person the date you plan to be done. Boring is the sign you are in the part that counts.
