The internet is the first thing in history that remembers teenagers better than they remember themselves.

Every generation before this one got to be forgotten by default. Their bad haircuts and worse opinions went nowhere, because nothing was keeping score, and they arrived at twenty five as a fresh person. Now there is an external memory that never updates its picture of you and has no idea you changed. That is a genuinely new situation, worth understanding rather than panicking about.

Keep a record you control alongside the one you do not. Notes on a phone, a folder of photos, a few lines written at the end of each month. It is the only version of your story where you are the author.
