Opening the book…
Plans are easy to worship because they feel like control. But nobody, at the end, wishes they'd guarded their schedule more fiercely. The people are the point; the plan was only ever the scaffolding. I've cancelled things I looked forward to for a friend who needed me, and I have never once regretted which one I chose.
When a person and a plan collide, lean toward the person, especially when they rarely ask. Take the call. Change the date. Show up for the hard day even when it's inconvenient. I try to hold my plans loosely enough that the people I love can always interrupt them.
Choosing people over plans can't mean abandoning every commitment on a whim; some plans are promises to other people. And a person who needs you to drop everything constantly may need a boundary more than your presence. Discernment, not reflex.
