Should I become an architect or a mechanical engineer?

I want some opinions of what to pursue. I really like building and designing, hands on sorta stuff. I always wanted to do stuff like that since i was a wee bit baby haha. I dont really know ( or cant decide ) what to become. I also like astonomical stuff like in the air or space stuff. If you have suggestions please comment! :D oh and also something with a good salary. Thanks!
