Hey, ya sound like me a few years ago. Me being a female, and a mother of two, it's really not a possibility to be a deckhand or captain. :) So I chose online retail and biology. (Just what everyone on this board is saying!) I actually started my major in something else and changed to a double major of biology and graphic design two years ago. And yes, I will pursue as a marine biologist, as well as keep my business going online.

There are many choices just as everyone said, but after doing a lot of thinking, there are really only a few that are profitable. I chose the two I thought most profitable. If I didn't have two children, (or was a woman) boy would I love to be a deckhand or a captain and be out at sea all day. (Not impossible in it's entirety seeing as Cpt. Greenlaw did it in The Perfect Storm) :)

Good luck in your decision and yes, college is a must!
