Someday someone will clean out your room and learn who you were from what you saved. Save things that tell the truth.

What you keep is an unintentional portrait, and usually a more honest one than anything you would write about yourself. The trophy says less than a ticket stub from a bad night you still remember, and the impressive items are the ones you kept for an imagined viewer. Whoever eventually goes through it is looking for you, not for proof that you were doing well. Truthful objects are the ones carrying information.

Keep one thing from this year that is hard to explain and easy to feel. A note, a ticket, a photo where nobody looks good. Put it where it will survive a move.
