Go work for a big 4 as a consultant in your specialty? Sure you’ll work 80 hours a week and travel basically all the time, but you get a lot of latitude and professionalism in exchange for that.
The culture in consulting has its problems, but things are getting better and we’re seeing a lot more women entering senior roles which is starting to fix some of the bad behavior that has traditionally gone on.
As for acting self-important? It takes a fucking ego to have a 27 year old kid tell a 50 year old SVP how to do his job. But as a result, people in consulting generally respect each others large egos, which gets you some degree of professionalism.
