In order of when they were first written my 23rd post is a private one
from July 1989, with only four sentences, the last of which is "If I don't do something soon I'll go crazy.".
In order of when first posted to livejournal the 5th sentence of the 23rd post
is "Looking forward to a couple of busy evenings before that, curry tomorrow, pub on Thursday, cinema on Friday to see Minority Report which looks vaguely promising in a Hollywood action film sort of way."
