I am one of those guys. I left for a big tech job even though doing research to push the boundaries of human knowledge was my dream. I know, a cliche, but I was a 20 something year old at the time.

The straw that broke the camel back was being treated like shit by my avisor for the nth time. I still remember it. He was like let's meet tomorrow at 8.30. I woke up at 6.30 to be there in time. He shows up at 10.37. Mind you, this happened like a 10s times over the 2 years I was doing my doctorate. And that was just one of the things he would do to undermine you and have the feeling he hold you by the balls. And he sort of did. Not being able to do anything because of potential repercussions was dreadful.

Anyway, after that day I decided it was enough. I slashed his car tires in the evening, still showed up for a couple of weeks to avoid suspicions, and only then formally quit.
