Stuck Drifting

Imagine you are trying to run on the moon. With each kick of your feet you only float upwards. You feel frustrated because while you are in the air, no matter how fast you move your legs, you go nowhere. You try to seize each sacred opportunity to move forward when you drift back down to the ground, but the harder you kick, the higher you get stuck.
I first had this dream during my senior year of high school after college decisions have been made. This dream re-occurred during my senior year of college after I had a job lined up and again a few months before starting my MBA. Last night, I had this dream again, but this time there are still decisions that need to be made. Although I seem to be leaning towards accepting an offer from McKinsey, there's a nagging voice inside telling me I should be pursuing a financial career. I'm getting desperate trying to find the source of this nagging so I can put it to rest once and for all.
