Dental Hygenist, or Anesthesiologist, or What?

I can't decide what I should do. I CAN do anything that I apply myself to, but I don't know which job would have the most benefits. So, please help me out. What would you suggest? =) Thanks. Almost any career is exciting to me, but I need something that makes money because my sister and I plan to share housing, and that needs to be pretty spacious housing. x)
