i celebrated by removing all the work equipment from my house & delivering it to the nearest company office which i never worked out of because i couldn't stand office politics. then i charged them for the mileage to deliver the goods.
i spent the first day clearing out all the corporate crap from my house. every letterhead, all the business cards, every scrap of paper, all the promotional pens. every every everything that had anything what-so-ever to do with that company including all the awards, all the reviews, everything but my pension information which i have put in a sealed envelope not to be opened for another 16 years.
then i brought in a local shaman and had my home office smudged with burnt sage.
