This one I saw someplace, can't remember where, but it's simple to remember.

At work, I have:
Hired people, fired people, made people audition for a job, swept floors, stripped people naked and reclothed them, ordered lunch for hundreds of people, fended off phone calls, encouraged phone calls, visited junkyards, chased a stalker out of the building, hauled boxes of books, sent someone home to change, been taken away by ambulance, upsold, met my husband, worn a tiara (same night, those last two), made a sale while having blood drawn, faked an accent, assisted a dentist (ew), called 911, pretended to be an authority on things I wasn't, helped with the inception of well-known organizations, been promoted, broken a very expensive decorative item and been congratulated for doing so, been offered a job while performing another, asked for a raise, fed a baby, made people happy.

I have never:
Waited tables, cleaned up vomit, been my own boss, changed a diaper, piloted a plane, used a hoe, been fired for cause, used an alias, used all my sick days (I am dumb), ratted on a co-worker except to their advantage which has always worked, made anything explode other than a lightbulb, been arrested. 

The 'I have never' is much, much harder.  I've done a lot of interesting stuff.
