The day after a birthday returns you to the life the celebration was meant to honor.

Celebrations are not a break from your life, they are a comment on it. The morning after can feel like a fall back into the ordinary, but the ordinary was the thing being marked in the first place: the years, the work, the people who came because of how you have lived among them.

Where the day after tends to feel flat, treat it as part of the occasion rather than the end of it. Do one small thing that belongs to the life you were celebrating. Call someone who was there, or continue the work the year is made of.
