If I had to pick i'd prefer being a doctor. They are doing something useful. But since i've never been good at biology and the like i've ended up doing something else.
I don't really like the lawyer profession though. They are helpful and required for many things but do laws really need to be so complex to understand that a elite group of people can understand and interpret them.... To me at least it seems like that industry shouldn't be as powerful as it is. also legal is really getting in the way of my work now. Having to be so careful of how to do something or risk getting sued.
