The lesson
Give away the full operating routine in the post itself, then hide the humblebrag in the P.S.
The post opens "My last 469 LinkedIn posts went viral. Over 2 years!" and lists a weekly plan: Monday motivation, Tuesday educational, Wednesday personal story, Thursday polarizing opinion. Rules follow (never schedule, an hour in comments, repost 6-8h later), then "Save + Repost". The P.S. quotes a "non-viral" post at 712 reactions, 471 comments and 62 reposts.
These are the author's own numbers about his own account, so don't borrow the 469 figure. Keep the day-by-day schedule and the closing P.S. twist.
