As a child I dreamt of being an oceanographer...then I grew up and realized that I have a strong tendency towards motion sickness. Not good.

I have one DREAM job:
action movie star
(I know...I'm weird)... it would be PERFECT for me though...physically demanding, I get to pretend (one of my favorite things to do in the world), super high intensity for a few months and then I get to do something else (like another movie or whatever)...never boring..

My realistic dream job:
Veterinarian
(I say realistic because in about 5 years I'll be bored with my current career path and I'll probably go back to school to start over...again...so I'm not ruling it out as a possibility).
