Worst are the meetings of international work groups. Stressful travel, being away from the family for days, sitting in a shitty meeting room talking about the same shit you talk about online and then sitting with a bunch of people getting senseless drunk, cringing constantly. I hate those meetings.
Used to be so awesome during corona. Took 4-6 hours, comfortably sitting in my home office, now it takes 3 days costing maybe 50,000€, instead of 0€, without more results.
