On a ski clinic 20 years ago, the guy running it pointedly didn’t want to know what our jobs/careers were. Only because he thought that he/all of us in the group, wouldn’t then subconsciously pre judge or pigeonhole each other.
A nice touch, it worked. You just got to know the characters...
Worst - staying at a firm where the owner spent every other day scheming against staff and ‘partners’ behind their backs, in a randomness based on who he’d loathed whilst not sleeping at night (genuinely).
Best - going it alone work wise. Do it people, it’s bloody amazing!
