Money shouldn't determine what you want to be. What do you like, and how much time are you willing to put into school? Personally I'd rather be making less money but be doing something I love, than making a lot but hate going to work everyday.
For me at least, I've always been creative and good with understanding how stuff is put together, so architecture made sense to me (since about 4th grade), and that's what I'm studying.
