I quickly noticed a pattern in the advice I received: the vast majority (90%) of people told me to do what they did. If they quit, then they recommended that I quit. If they stayed and the company and climbed the corporate ladder, then that was the path for me as well.
The idea that people convince themselves of their current work situation (or relationship, or car, or political beliefs) to maintain sanity--cognitive dissonance--is something I've observed a lot since I've learned of it.
'Tis good to ponder such things.
