I keep hearing that consulting and finance are terrible uninspiring careers, but as a consultant I honestly have no idea what else I could do that would be more inspiring. I would love to know though.
There are no other better choices available, unless one is born into wealth. That's why whoever talks about passion, inspiration, etc, is just talking throgh his/her hat. For 95 percent of the world population, some job is better than not having a job.
There are plenty of things which are more interesting than consulting which is why most consultants actually use the career as a stepping stone to go do what their clients were doing.
