Can i have two careers at the same time?

I have a hard time choosing between these two careers (almost out of high school)?

• pretend nothing is preventing you from doing either of these two jobs/careers: working on navy ships or spaceships. I have a hard time deciding which one to choose and here's why? I LOVE aircraft carriers and how they are huge drivable compact cities. In fact I got to take a tour of an aircraft carrier once and it was UNBELIEVABLY HUGE and like a huge maze and city inside of it. But I also Love spaceships and used to watch the space shuttle dock to the space station on TV. Now there's going to be space tourism within the next 20 years and I want to help build spaceships so civilians can go into space, but chances are they won't be huge drivable compact cities like aircraft carriers are. Which career should I choose out of these two? Is it possible to do both? Do you think within my lifetime we will have ships big as aircraft carriers in space along with orbital shipyards and dry docks?
