Your lock screen is a picture you chose to see a hundred times a day. Check whether it still says something true about you.

Something that crosses your eyes dozens of times between waking and bed is doing more work than its size suggests. The choice was made once, maybe eighteen months ago, and it has been running quietly ever since. It reminds you of something, and it is worth knowing whether that something is still one you want.

Look at it properly rather than through it, the way you look at a familiar road sign. If it belongs to a version of you that has moved on, change it this afternoon, since the whole operation takes ten seconds. Pick something that points where you are going.
